While the littlest one was sleeping, my daughter and I made bath fizzies. The recipe was easy.
-1 c. baking soda
-1/2 c. citric acid (I'd never heard of this. We bought this at Sprouts Market, but I had to ask where to find it. I thought it would be a liquid but it was a powder. Surprise!)
-1/2 c. cornstarch
-2 T. coconut or almond oil (we used coconut, also found at Sprouts)
-1 T. water
-food coloring (optional)
You simply mix all the dry ingredients in one bowl and mix the water and oil in a different bowl. Put the two together and mix, mix, mix. The consistency is about that of moon sand. The next step was to shape the mix into balls and place them on a baking tray.
This is the way my little girl lined them up. Later I learned that I needed to spread them out a little more because these puppies get a lot bigger.
They need to dry for 24-48 hours. It's really interesting to watch the process. First they get sticky, then they get dry and hard.
This was a really fun project and the kids love tossing them in the bath and watching them fizz.
