At Wonderama, we love making blue bubbles and a science experiment is our favorite way to do just that!

In our first installment of Cool Science with Rachel, we combined hydrogen peroxide with dish soap and yeast– oh, and a drop or two of food coloring for effect– to create what the scientific community terms “a big mess.”

Wonderama Rules:  Safety first. Wear safety glasses and alway ask permission and be supervised by an adult when conducting an experiment.

[li]What you need[/li]
[li type=”glyphicon-ok”]Saftey Glasses[/li]
[li type=”glyphicon-ok”]A beaker or clear  16oz soda bottle[/li]
[li type=”glyphicon-ok”]1/2 cup of hydrogen peroxide[/li]
[li type=”glyphicon-ok”]1 Tablespoon of dry yeast (one packet)[/li]
[li type=”glyphicon-ok”]3 Tablespoons of warm water[/li]
[li type=”glyphicon-ok”]Liquid dish soap[/li]
[li type=”glyphicon-ok”]Food coloring[/li]
[li type=”glyphicon-ok”]Small cup[/li]


[li]How to do it[/li]
[li type=”glyphicon-arrow-right”]Carefully pour the hydrogen peroxide into the bottle[/li]
[li type=”glyphicon-arrow-right”]Add 5 – 8 drops of food coloring into the bottle[/li]
[li type=”glyphicon-arrow-right”]Add the dish soap. The more the messier! Carefully mix[/li]
[li type=”glyphicon-arrow-right”]In the small cup, combine the warm water and the yeast together and mix for about 30 seconds[/li]
[li type=”glyphicon-arrow-right”]Pour the yeast mixture into the bootle and STAND BACK![/li]

Basically what happens is an enzyme in the yeast, called catalase, breaks down the hydrogen peroxide into oxygen and water in a rapid chemical reaction. The oxygen gets trapped by the dishwashing detergent, creating many tiny bubbles that can’t wait to escape the beaker. So cool!


The fizz reminded David of a slushy (blue-raspberry, perhaps?), but as Rachel said, “I wouldn’t put it in your mouth!”
