Ryan!

Experiment:  Fantastic Foamy Fountain

Objective:  How to create an exothermic reaction

First, Ryan and his assistant, Mom, carefully measured out hydrogen peroxide...

…and poured it into the plastic soda bottle. 

Next, he added a tablespoon of dish soap to the bottle.

Then Ryan added 8 drops of blue food coloring to the mixture.

After that, Ryan shook the bottle to thoroughly mix the three ingredients in the bottle.

Now the fun part!  

Ryan added a yeast mixture, the catalyst or "helper", 

to the mixture in the bottle...

…and we watched the blue foam erupt...

…and erupt…

…and erupt some more!! 

What a fun experiment, Ryan!

Ryan told us the experiment is nicknamed

"Elephant Toothpaste"!!

Conclusion:  The yeast helps to create the reaction to remove oxygen from the hydrogen peroxide to create foam and heat.

Super job, Scientist Ryan!
