Foamy Yeast Eruption

In this instructable, i will be demonstrating the chemical reaction between Hydrogen Peroxide and Dry Yeast.
This is a great experiment that i use when teaching my science class.

Step 1: Materials

Materials:
Hydrogen Peroxide
An empty soda bottle
Dishsoap
Dry yeast
Measuring cup
Empty cup
Small spoon
Measuring table spoon

OPTIONAL:
Food coloring
Funnel

Have you ever done more than one color at once? I'm wondering if you took a bottle of red, yellow and blue and had them go off at the same time or close to the same time if the foam would mix and change colors. I'm an art teacher and I think it would be a really fun and memorable way to explain color mixing. If you haven't, I might give it a try and pass on any info I gain from it. :) Again, great 'able. I can't help but smile and think of Sheldon. (I LOVE the Big Bang Theory)

Good idea, i might try it:)

Oh my this is funny! It reminds me of an episode of Big Bang! Well done!

Very impressive. Does the mixture is hard after?

[TheScienceMan]

No it isnt.

1. your video is marked private.
2. What is the chemical reaction going on? The yeast eating the hydrogen peroxide, waste gases when yeast is sterilized, soap frothing up?
