My Prediction

What I think will happen?

I think that the hot water and the chemicals in the hydrogen peroxide with the yeast (which is alive and sleeping but wakes up when you add hot water) will cause a thermal reaction and make the ingredients turn into foam.

What happened?

I added all the ingredients and used a red food coloring and i got a lot of bubbly foam.Caution: The foam will be hot because this is a thermal experiment.

How do we make a bubbly foam???

1. take 120 ml of hydrogen peroxide (H202) 40%and pour it in a beaker or medium sized flask..2. take 2 squirts of the original green palmolive dishwasher soap and add it with the H202.3. in a smaller beaker or flask take 2 teaspoons of active dry yeast and pour.4. take hot water (hotter than 100 degrees) and pour until the cup is 3/4 full.5. mix the yeast and water with a wooden skewer.6. add any food coloring colr you like to the H202 solution for some nice color.7. add the smaller beaker of yeast soluton into othe solution and wait for reaction. the color you chose will be the color of the foam.
