This experiment uses a yeast solution, liquid detergent such as Dawn, and hydrogen peroxide to produce an exciting reaction like no other! The result will send a stream of foam shooting up out of a bottle and, after a minute or so, begin turns into a moving stream that resembles toothpaste being squeezed from a tube. You may not want to use this foam to brush your teeth, but you'll certainly “foam up” your child's imagination and love of science!
What You Need:
- 16 oz. empty plastic soda bottle
- 20 ml (0.675 fluid ounces) hydrogen peroxide (6% solution, purchased from a beauty supply store)
- 10 ml (0.3382 fluid ounces) dishwashing liquid (such as Dawn)
- Food coloring
- 1 oz. package of powdered yeast
- Small Funnel
- Aluminum foil cake pan with 2-inch sides
- Safety glasses
(Although the following activity is safe it is always good practices to have your child wear safety glasses whenever they conduct any type of activity that involves working with chemicals)
