We love our Magic Foaming Stars so so much that we just had to put a Halloween spin on it! I love this activity so much because it's super easy and quick to set up and the results are crazy cool.
Start with a mama spider.
Add her to your vinegar and watch the colored rays of soap foam shoot out!
Add more spiders and watch the shooting foam rays grow into mounds of fluffy colored foam.
As the mama spider foams, her little baby spiders hatch! Rescue them!
Got a baby!
Eventually the spiders disappear, leaving behind mounds of fluffy colored (icy cold) soap foam!

Baking Soda (aka Sodium Bicarb)
Dish soap (aka Washing up Liquid)
Food Coloring or Liquid Watercolors
Small Plastic Spiders
Take two pipecleaners, fold them in half and cut them. Fold the cut-in-half-pipecleaners again and then cut one more time. Bend each of the eight pipecleaner legs slightly and set aside. In a bowl, measure out 1/2 cup of baking soda and add 1/4 cup of water (if you'd like to add liquid watercolors or food coloring, add them to the 1/4 cup of water). Mix well until all the baking soda is damp and all the color is well distributed. Grab a handful of the damp baking soda and add some small plastic spiders to the center. Add another handful of the baking soda on top and mold it into an oval (spider abdomen). Place the abdomen on a sheet of wax paper (using a tray underneath the wax paper will make it easier to move). Add four pipecleaner legs to each side of the oval spider abdomen. Next, take the remaining damp baking soda and form a head. Place the head such that it is pressed firmly against the body - this will ensure that the head and body freeze together (and you won't accidentally decapitate your spider). Repeat for as many spiders as you'd like to make. Move the finished spiders to a freezer for at least 6 hours or overnight.
Prepare a shallow bin or dish with vinegar and several squirts of dish soap (2-3 squirts per spider is a good rule of thumb). Swish gently - just enough to barely mix the soap and vinegar. Add your spiders and watch colored foam shoot out as they slowly dissolve. :)

All activities here are activities I feel are safe for my own children. As your child's parents/guardians, you will need to decide what you feel is safe for your family. I always encourage contacting your child's pediatrician for guidance if you are not sure about the safety/age appropriateness of an activity. All activities on this blog are intended to be performed with adult supervision. Appropriate and reasonable caution should be used when activities call for the use of materials that could potentially be harmful, such as scissors, or items that could present a choking risk (small items), or a drowning risk (water activities), and with introducing a new food/ingredient to a child (allergies). Observe caution and safety at all times. The author and blog disclaim liability for any damage, mishap, or injury that may occur from engaging in any of these activities on this blog.
