The kids wanted to participate in the science fair this year at school. I could not bring myself to do three different experiments so we did the same one three separate times and they will each get to do their own boards. The end of the year is upon us and I am about at the end of my rope.
We made elephant toothpaste for the experiment and it was so much fun. Dish soap, peroxide bleach, some food coloring. Add yeast and watch the fun!
The experiment is exothermic but the end result is simple soap foam. Perfectly safe for the kids to play with. They were so excited to play with the results!
