Ever since I created the bath bomb recipe for our Hatching Dino Egg Bath Bombs, we've been addicted to bath bombs. They're just so much fun! Not to mention they are inexpensive and easy to put together - a total win in my book. :) With fall here, I thought I'd try my hand at making some scented pumpkin bath bombs. We love how they turned out!
Cute little pumpkins! Once they dry they are easily handled. Of course if you happen to drop one on the floor, all bets are off. Still fun in the bath, though, even if they get broken.
It's practically impossible to photograph bath bombs in action! I set this one in a shallow dish of water so you could get the idea. You can probably make out a few bubbles. It bubbles SUPER rapidly, so it's hard to catch them all. When you submerge them in a bath they send all the little bubbles up to the surface - so fun! The reaction is endothermic (it requires energy, so it absorbs heat from the surroundings), so the bath bomb itself gets very cold to the touch.

Depending on the size of your pumpkin cookie cutter, this recipe may make slightly more or slightly less than 8 bath bombs.
A pumpkin cookie cutter (you could also shape them by hand if you want, but the cookie cutter makes it easy/fast)
Baking Soda (AKA Sodium Bicarb)
Liquid watercolors or food coloring (optional)
Add 1.5 cups of baking soda and 1 Tablespoon of cinnamon to a bowl and stir well. If you want to make green stems, set aside a small portion of the baking soda in another container. Add 3/4 teaspoon of liquid watercolors (or a few drops of food coloring added to 3/4 teaspoon water) and mix well by hand until all the color is evenly distributed (I added a much smaller amount of green to the bit of baking soda I set aside for the stems). Add 6 Tablespoons of Citric Acid Powder and mix until evenly distributed. Some of the Citric Acid Powder will react with the small amount of water you added to add color - the mix will be very cold to the touch. Don't worry, that's normal - and there's still plenty left to react when these hit the bathwater. Finally add 2 teaspoons of olive oil and mix well. You should now have a dry dough that holds together when squeezed. Pack the dough into the pumpkin cookie cutter and, applying pressure to the center and using a steady hand, remove the cookie cutter leaving the "dough" behind. Allow to dry for 1 hour or more. Then add to a bath (or a dish of water if you'd like to play with them outside of the bath)! The cinnamon smells awesome and is often added to baths to fight germs (which works well with fall, right?).
You can buy Citric Acid Powder online or you can find it in some grocery stores that have a bulk spices section. It's used as "sour salt" for candies and as a preservative in canning, so I always find it alongside spices.
