I was talking to my friend Emily again the other night (after we'd made our blue Edible Glowing Oobleck) and she convinced me to see what other safe and edible things I could find that glowed.  Though tonic water glows, it's very smelly if concentrated, and I have not been able to find any tonic water that doesn't have a ton of high fructose corn syrup.  So tonic water, while a safe glow water, had its limitations: a smelly sticky bath just wouldn't work for us.  I wondered if there were any alternatives to tonic water to create a safe glowing water for kids to play with (or if I could even find a glow water that would be safe to add to a bath)!


A little Googling found me this list of things that fluoresce.  Some more Googling led me to believe that I wanted a B vitamin high in Thiamine if I wanted a really great glow with a blacklight.


So off we went to the store to see what we could find.


We found just the perfect vitamin, and brought it home.  To make our safe glow water we combined:

Two of this vitamin, crushed <---- CLICK for the vitamin details
(Each brand calls it something different - to be sure you are getting the correct vitamin (not all glow brightly), either buy this one via Amazon or write down all the ingredients and amounts and find a B vitamin whose ingredients match these at the store)
Warm water

Using a kitchen mallet and ziploc bag, S helped me pound the vitamin into powder and we added it to a glass of warm water and she stirred.  Once it was pretty dissolved, we added the cup of vitamin water to a tub of regular water and swished it around.  Now just to be totally clear, though this is edible, it's not intended for kids to just drink down by the cup full.  The vitamins are adult strength.  They are super diluted of course, but please don't serve your child a cup of glowing bath water.  :)  It is, however, not a problem if they accidentally splash some in their face or mouth, or get a stray mouthful or two.  For those of you with concerns about absorption (There is no research indicating that this amount of dilute vitamins could/would be dangerous in any way and my pediatrician's office confirms that this amount is too dilute to absorb through the skin), you can dramatically reduce the amount of vitamin per several gallons of water and still have a great glow.  For reference, this is about the amount in an energy drink.  If you have concerns about the use of a blacklight, I again encourage you to contact your pediatrician.  As with all play materials/activities, the decision is yours.  :)


I originally intended for the kids to play in a big bin of water, but couldn't find one that would fit in the tub while they were there.  And the brilliant thing about this is that it is super safe.  It's not sticky.  It's just perfect for a glowing bath.  So that's what we did!

This post contains affiliate links for your convenience.

Though our bath glowed brightly with just one crushed vitamin, it was even brighter with two, so that's what we ended up doing.  I did a bunch of digging on Amazon and found this vitamin (UK link to the vitamin) (Aussie link to the vitamin) whose composition exactly matches our store-bought vitamin (and if you make your baths the same way, it will cost you on average just pennies a bath - cool!).  If you want this very vibrant glow I'd recommend either buying the one I linked to or jotting down the quantities (there's a photo in the Amazon store that lists all the information) for when you go to the store, as I suspect the results vary a lot depending on the vitamin's composition. Ours was Kroeger Brand, if that helps anyone.  You will also need a Blacklight, as this is a fluorescing reaction - not a glow in the dark (like a glow-in-the-dark paint might be).**

**Please use caution with a plugged in blacklight and water, as you would with any plugged in device and water - use with a GFI outlet - standard to all bathrooms built to code**


Rather than make a fancy bath (I just am not that creative!), we just collected several items we already had that fluoresced (it was a fun scavenger hunt!) and added them all to the bath:
White Dollar Tree Funnels
Boon Bath Shapes 

  X was again totally fascinated - they both loved it so much!

    2. Vitamin B is a water soluble vitamin, which means even if the kids did absorb it through their skin, ( i honestly don't know if it can or not) their body would excrete the excess through their urine, so it should be safe.

    3. Make sure you are plugged into a GFI recepticle!!!! (ground fault) You don't want to have a accident.

    4. How many vitamins do you have to use???

    5. Between 1-4 will give you a good glow, depending on how much water you put in your tub. We used 2 for the photos. :)

  2. I'm confused, do you have to have a black light in the bathroom for it to glow? I'm assuming it's just bright yellow otherwise.

    ReplyDelete
    Replies
    1. Yes, it is a fluorescent reaction, like with our glowing oobleck - and you will need a black light. It's kind of an orange color in normal light. :)

      Delete
    2. you can actually just buy a black light bulb at home depot and srew it into outlet in your bathroom and use that ---that way there is no chance of electrocution-i can put it into one of my bulbs that go around my mirror---unscrew other ones so they aren't glowing

      Delete
    3. I think it will depend on how far your tub is from the light bulb - sometimes those are so weak that the blacklight light won't reach the tub. As long as your bathroom was built to code (legally), it will have GFI outlets that prevent electrocution. But for sure that would be a great option if your bathroom light is close enough to the tub for the light to reach it! :)

      Delete
    4. Where exactly was your black light? We have a recessed can light right above our tub.

      Delete
    5. To my knowledge, no one has tried one right above their tub - that just might work! I would keep your receipt, just in case, but I think it's worth trying. If it works, would you be willing to come back here and let us know?

  3. Looks a LOT of fun!

    Vit B is water soluble so there should not be any risk with kids drinking it. It's the fat soluble vitamins (D,E,K,A) that can accumulate in the body and cause toxicity as far as I know.

    2. So the vit is Vit B any certain strength?

      Delete
    3. The link to the percentages of each type of B vitamin is in the post - so be sure to get that one or one as close to that as possible, because many B vitamins glow much more faintly. The concentration in the photo is two vitamins per the whole tub of water, but you could get away probably as little as a half of a vitamin per tub, the glow would just be less concentrated. I hope that helps!

  5. This is great! I can't do the "highlighter" version of glowing baths because my ds is super allergic to dyes. He is allergic to vitamins too, but only if he eats them. He is old enough not to drink the water though, so this should work.

    How do you mount the blacklight so that it doesn't fall into the bath?

    ReplyDelete
    Replies
    1. Hi Levi's Mommy! Oh poor bubba! That sounds really rough. I actually just held the blacklight because it was easiest, but there were little holes in the back and screws if we wanted to mount it more permanently.

      Delete
    2. Blacklights just need to be in the area to illuminate fluorescence. You can get a 24 inch light at Walmart for around $15 and just sit it on your counter, facing the bath and it should light the same. If you have a light in your bath, you can also swap the bulbs with a blacklight bulb and leave the cover off, though less powerful.

      Delete
    3. Our light is over our sink, not over our tub. I was wondering if just a blacklight bulb would work.

      Delete
    4. Totally not sure on that one Michelle...? Maybe?

    5. tried to do this with just a blacklight bulb and couldn't get any fluorescent action....

      Delete
    6. Bummer, Anonymous! I bet the bulb doesn't have as great of a reach as the tube lights. Well, Michelle - it looks like you'll need a tube light.

      Delete
    7. Working with black lights it depends on how far away the bulb is from the luminescent object and the wattage of the bulb affects it as well, kind of how a 100w fluorescent bulb is brighter than a 60w.

      Delete
    8. Oh, good to know! Thank you!!!

    9. A blacklight or 2 directly above (ceiling mounted) that are battery operated could be an awesome alt to the dangerous plugin versions, if you are worried about the blacklight mounts not working or being too weak you can get a safety net or a stuffed animal corner net (2 of those would work fine) and mount those above the bath just below the lights so you dont need to worry about that either, just remember to make sure you keep a clsoe eye on your kiddos so they dont think the net is a gymnasium or other climbing toy :D!!!

    10. Thank goodness ... I know nothing about 'black lights' but do know that in the UK we are unable to plug ANYTHING in in our bathrooms as we are not allowed to have a light switch or a socket in there save for the shaver. I was hoping that there was a battery version ... as my grandchildren back there in the UK will love this !! (Along with their mum!!! )

  8. Could you bathe the kids normally in this? Could they still get cleaned up and their hair washed or would they have to be rinsed off or given a regular bath afterwards?

    ReplyDelete

    1. Hmm, I don't know that I would, but theoretically you could. The vitamin isn't sticky or anything, but it does have a slight vitamin smell. We just drained the tub and rinsed the kids with a little water. I didn't seriously scrub them or anything and they were fine (and didn't smell funny, LOL).

    2. and if you don't rinse, they will be easy to find in the dark, with a black light flashlight! :)

  9. While the effects of the Vitamin and water have been scrutinized for possible dangers, I see that black light has not been considered, which is quite dangerous and exposure for half an hour is considered bad for eyes and skin. Have a look here for more information.

    1. Hi Anonymous! I did research blacklight safety and couldn't find anything that stated that a short amount of exposure would cause any harm:

      http://en.wikipedia.org/wiki/Blacklight#Safety

      I agree, though, you wouldn't want your kiddos to sit in a room with a blacklight for hours every single day. Ultimately, as with exposure to anything - a tub full of water, sunlight, etc, the choices are up to the parents.

      Delete
    2. Leave it to someone to ruin the fun. Its not like our kids will be in a tanning booth! And not for long

      Delete
    3. I actually thought the same thing. It seems like a lot of research went into the vitamin exposure, but the whole time I was reading I was thinking, "But you're using a black light!" It's not the worst thing ever, but it can be damaging.

      I think the idea is pretty cool though.

      Delete
    4. If you're concerned, iloveapiano, I suggest bringing it up to your pediatrician. Blacklights have a weak UV output. Also, as I'd say with any of our activities - different people have different ideas of what is acceptable for their kids - so feel free to pass on any/all activities that make you uncomfortable! :)

      Delete
    5. Actually, I'm glad that people like the original Anonymous poster and iloveapiano had the sense to comment on the possible negative effects of using a black light because I had not considered the dangers of exposure.

      The proper thing to do when you are making an "activities for children" blog such as this is to list all the possible dangers (whether you personally feel they are insignificant or not) and let parents decide for themselves what is appropriate for their child. Instead of, you know, basically telling someone that their concern is invalid and "well you don't have to participate if you don't want to".

      Delete
    6. I'm so sorry you feel such anger toward me, Anonymous! I am not trying to deceive anyone at all. As I stated in the post and in my disclaimer, I suggest parents discuss any and all activities with their pediatrician. I discussed with mine and they said there were no issues - your pediatrician may say the same thing, or they may have a different opinion. Life is full of risk - in fact, placing a child in water is a HUGE drowning risk. Playing with any item larger than a sesame seed is a choking risk, playing with a food or chemical ingredient can cause an allergic reaction. I am not trying to be rude by saying you don't have to participated if you don't want to - merely stating a fact. Some parents do not feel comfortable exposing their children to food coloring in play, some do. Every activity has risk and every activity is bound to have one ingredient or item that could be something that parent is choosing to avoid with their child. It is not my place to say whether or not food coloring, wheat, corn, pom poms, water, or blacklights are safe or not. All I can offer is what my research (including speaking with my childrens' doctor) has shown. It truly is up to each individual to make the choices for their child and their family. If I listed every potential danger of every activity it would be too time consuming. Thus the blanket disclaimer you will find that applies to every post on this site. I'm sorry that you feel I am not sinking enough of my own personal time into this FREE RESOURCE for you.

    8. I am "another" different anonymous person that finds it both funny and disgusting to read the above comments from the anonymous persons and the ilovepiano person!!! I do recall reading in the first few lines of your blog about checking everything out with your child's own pediatrician or to do further follow-up online if you had any other concerns regarding the use of this product, the amounts to use, and the use of a black light. Maybe "people" should READ the whole post/idea before they start to bash it. "PEOPLE WITH CLOSED MINDS HAVE OPEN MOUTHS!!!!!!"

    9. Ok, this is the third time I am going to try and comment on your anonymous critics. I have posted twice already and apparently my comments aren't appreciated because they are not being posted, which in my opinion is ridiculous because they felt it was appreciated and appropriate to post the "anonymous" comments from two separate people, which has really sent me through the roof but as they say, those with closed mind have open mouth.....if that helps you at all. Just as the last anonymous poster had mentioned, if you are concerned about "YOUR" child taking part in this type of activity, then I would think that "YOU", being the child's PARENT would want to take the time and look up the information that you so graciously had posted...so, I am not really understanding what their point is in all of this? Maybe someone else can explain to me?? Yes, just so its out there, I do have a child and if there were something that I would love to have my child participate in, but I knew that there may be a small risk in participating in this, being the child's parent I would take it upon myself to look into every website available until I was certain that it would be safe for MY child!!!!

    11. I think this is great! To each their own but come on people a fun activity you will probably do once is not going to harm your children by using a black light. We grew up around them. Protect your kids yes,but don't smother the poor things. I can see these kids running around bubble wrapped,but then again watch out they could suffocate. Yes be cautious of the light it could fall in but your exposure is not a everyday occurance your child will not come out with a tan or skin cancer.

  13. Does the B vitamin have to be a complex or can it be straight up B1 (thiamine)? My daughter loves oobleck so wanted to try the glowing kind with her. Also, do tonic water and the vitamin water glow different colors? Thanks!

    ReplyDelete
    Replies
    1. Hi Anne! All the B vitamins will glow to different extents (and different colors - some are more yellow and others are more blue/white). I didn't want to spend the money to investigate with each individual vitamin - so my recommendation is if you want the bright glow we have here, make sure to find a vitamin with the same composition as ours. Otherwise you can experiment a bit - but some may not glow very vibrantly. Tonic water is more of a blue/white and the Vitamin Glow Water is a bright yellow/green. Hope that helps! :)

  14. hi. sorry didn't see this particular question above or in your instructions:
    1) did you pound the whole bottle of vitamins at once?
    2) how much crushed vitamin did you add to one glass of warm water?
    3) did you use only 1 glass of this mix for each bath or more?

    1. No problem! Always happy to clarify!

      1. You could if you wanted to, but I generally do the 1-2 I am using at a time.
      2. However much you want to use. I just found it easier to mix it well in a small glass before adding it to the bath. But if you were willing to vigorously stir the bath, you could always add the crushed vitamin directly.
      3. I did only use one glass - isn't that nuts? It's REALLY bright. This is just two vitamins total.
      You're welcome! I hope you love it!!!

    1. While I can't guarantee anything, no we have had no trouble with this staining. It contains no dyes, just natural color - and it's so diluted, it has never even shown up when it gets on clothes/skin/tile. We wash everything right afterwards, just to be safe, but it is NOTHING like highlighter. That stuff stains everything! The glow game sounds awesome!

    Replies
    1. It's REALLY hard to get photos on your camera in the dark. The shutterspeed has to be extremely low - and for most regular (not specialty) cameras, you'll need a tripod to get photos with such a low shutterspeed. We do hold our tube blacklight in our hands since we don't have a ceiling mount in place, but I suspect if it was glowing brightly, it's just that your camera was unable to slow the shutterspeed down enough to grab a dark photo.

    1. I am not sure since I've never tried it, but I can't think of a reason why it wouldn't work --- other than a pool has a looooot of water. So you'd need a lot of vitamins. And probably several blacklights to fluoresce that much water. You could always try it with a sample of pool water and a blacklight to make sure that it would still work? If it does, let us know!

  20. I don't remember reading exactly how you did it besides vitamin b. What else goes into this glowing madness? Also another question when ever you play with it, is it like a glob you can pick up and move around or when you touch it it would dissolve in the water. I'm a high school senior with a two almost the year old sister.

    ReplyDelete
    Replies
    1. Make sure you get the correct vitamin (check out the link to all the ingredients in it and find one that matches or buy that one) and then crush it and dissolve it in water. It just feels like regular water, but it will fluoresce (glow) brightly if blacklight light hits it. The long (tube) blacklights will make it glow the most brightly. Hope that helps! :)

My point is to differentiate this from highlighter water and paint filled water, which were the previous methods offered as "safe for kids". :)

This us just to play in and for fun if you really where to hand them a cup of it to drink then you shouldn't have kids to began with. I mean really what is this world coming to that she actually has to warn you about these things!

    1. Nowadays, a lot of people grow up and have children having never been around little ones. Many things that were "common sense" because they were well known, aren't so commonly known anymore. Some people have babies and love them but do not have the advantage of wisdom being handed down from one generation to the next.

  27. Wait what is the vitamin called?

    ReplyDelete
    Replies
    1. Beth, I've seen it called five different things - so the best way to get the correct one is to write down all the amounts of B vitamins in the link above - or to buy the one in the Amazon listing it links to. It's a common enough vitamin that you should be able to buy it at the store if you want to - but every brand of vitamin has a different name for it. Best to rely on the ingredient list vs. the name. Hope that makes sense!

  28. My daughter is almost two and absolutely loves the "tub tub". We have a very large two person tub so I bet it will take a few more tablets. LOL! We are going to save up and buy a new backlight and try this out as soon as we can! My daughter is going to go crazy when she sees it! I am going to start looking for backlight reactive toys to play with in there. Thank you for this awesome idea!

    1. Oh I hope she loves it! We were surprised at how many of our toys were blacklight reactive - try out anything white or neon colored that you own - you may already have some! :) :)

    2. Just get a black light bulb and screw it into your light socket in the bathroom.

      Delete
    3. It depends on the location of your bathroom light - sometimes the light from the screw-in bulbs has a hard time reaching the bath water if the light is located on the opposite side of the room.

  29. How long does the glowing last? There's all kinds of neat applications one could use this for, to make things, but the glow has to last. :-)

    1. Oh yes, lots of fun to be had with it for sure! It lasts indefinitely, so far as we can tell. You have to have the blacklight on it, of course, but the vitamin doesn't break down or anything. It may settle a bit over time - that's the worst of it!

    1. As I stated above, no that's not possible. I have spoken with several doctors about this, and you are welcome to ask yours and hear the same thing. For something like that to be absorbed, it would need to be hyperconcentrated - like a very thick paste.

  37. When I used the link provided to look up the vitamin, it sent me to Vitamin B-50 Complex. Is this right.? I got the same one when I used the site for the UK also. It gave me the ingredients., but it also was for capsules not tablets. Which is much easier, but confusing, since you used tablets and did not mention complex or B-50.

    ReplyDelete
    Replies
    1. For that brand, yes, B50 is correct. The one we bought in our local store is called B Complex, and I've also seen it called Super B and a few other things. For some reason the name varies with the brand. It doesn't matter whether it comes in tablets or capsules in terms of working - so long as you have a hammer or mallet, you can break up the tablets very quickly. I don't mean to be confusing - it's just that if you buy another brand's B50, it might not have the correct ingredients. All the links are to vitamins with identical ingredient amounts.

  38. I didn't read all of the comments to know if someone already addressed the B12 not working. It won't work. The only B vitamin that you need is B2, or more commonly called Riboflavin. The problem is that it is hard to find by itself, so you have to find a B vitamin complex that has it.

    ReplyDelete
    Replies
    1. I was just coming here to make a similar recommendation, B-2 is the stuff that actually fluoresces, they even use it in some industries to check systems for leaks! You can get straight up B-2 on Amazon just like the Complex you linked in the article, same price, but it's strictly B-2 and one capsule will make an entire bath SUPER bright. Pharmacies will carry it but not stock it, so if you would rather do it that way, hit up your local Walgreens or whoever. It's actually pretty easy to get, as long as you don't expect to pick it up in person at a store. :)

  39. My 16 year old has nothing but black lights in his room. Both on his ceiling fan (5 of them) and 3 bars mounted to his walls. He has had them for 3 years.
    He has had NO NEGATIVE outcome from them. No depression, no cancer, no skin issues, no brain malfunctions (other than being a teenager).

    So, on that note, I don't think a 20-30 min bath, say even once a week with black lights is going to cause harm.

    Parents today don't allow kids to have a life and try to protect them from even their shadows. All that is being accomplished is there is a society of stressed out, uptight, spoiled kids with no common sense, and no street smarts being raised.

    Let loose. Let kids live on the edge a little. A little black light and a glow bath never killed anyone!

  40. I Love this idea and thank you for the Share .. As has been said above this is a experiment that Asia Citro did , if you think of any concerning issues then I suggest that you be a responsible parent and research your issues or talk to your family doc. you do what you need to do to make sure your own child is safe with any experiment. I Appreciate the time and effort that went into this post and if I can think of any serious issues I will research for my own piece of mind .. Thank you again for this great Idea ... Love it :)

  43. I'm not sure if anyone else has mentioned this, but vitamin B is a water-soluble vitamin (as opposed to vitamins A, D, E, and K which are fat-soluble) so it's totally safe. Even though it's "adult" strength, any excess vitamin B in the body is flushed out through the urine and is not stored like fat-soluble vitamins. It's practically impossible to get a toxic dose of vitamin B. If you're still concerned, by all means, contact your pediatrician. I'm not a doctor - I'm only a college student studying health information (I've take anatomy and physiology and pathophysiology), I have a cat who has IBD with a vitamin B malabsorption issue (so I'm pretty familiar with how vitamin B works in the body) and prior to becoming a student I was a vet tech for several years. I'm no expert, but I do know a thing or two :)

I know that there are "Glow Run" races where they manage to make everything glow - but I have no idea what sort of blacklight set up they have to do that. I think your best bet might be to see if you could get a neon bounce house/water slide and to have several blacklights set up, but even then I'm not sure. I wish I had more information for you! Good luck - it sounds super fun!

I'd recommend using either a flashlight or a tube light (we use the 2ft long kind and it works great!). Hope that helps!

  57. Yes Tonic water will Fluoresce but the fluorescing ingredient in it named Quinine, if not used properly can cause major illness and even death. Please type in "Quinine" in Wikipedia to learn more. In Tonic water it is very diluted, and that is OK, but avoid using Quinine Powder in your Bath if you have access to it. In Australia it is a banned substance for consumers to by. I hope this information is OK.

  61. I work professionally with blacklights. Commercially available blacklights are fine. They are very similar to a purple light as far as skin or eye sensitivity. I work all day exposed to these. There is no risk. Look up long wave blacklight. There are dangerous types of uv radiation that you will find in tanning beds or other industrial applications. Most blacklights are a regular fluorescent tube with a violet filter. Awesome idea! Just dont buy from an industrial supplier:) if it costs 300 +dollars it could be dangerous . Buy the 25 or less one and you cant go wrong. The dangerous ones cost a lot.

  64. The flourescent tube blacklights are much better for this application than the light-bulb style. The tube number you want will end in "BLB" (for "black light blue" - that last character is important since it means the bulb has a built-in purple filter to block most of the visible light it creates) You might have to special order the tubes if your bathroom uses a 4 foot fixture (locally, 4 foot blacklight tubes are $42 each, but the more commonly-used white-light tubes are only a couple of dollars apiece)

    Many types of plastic will block this (invisible to us) color of light. If it can be done safely, a bare tube several feet away will produce brighter results than a plastic covered one that is closer.

    If using an older film camera make certain to use a UV filter because film is much more sensitive to blacklight than to visible light. Leaving the filter out will result in a washed-out effect, not the vivid colors we see.

    For a battery operated blacklight flashlight, try stores supplying those into rock collecting or watchmakers. The former use it to identify certain types of rocks, the latter use it to harden a special type of glue used on watch lenses.
