Chemistry

Today I did chemistry, it was pretty cool because we made some Elephant Toothpaste.  When we put yeast in and it rose up up up.  It looked like it was toothpaste because some of it had stripes in it.  Mine didn't.  I did yellow and green food colouring but I over did my yellow so I only got yellow.  We saw this video of some chemistry it was outside so they put all the stuff that we did except food colouring and it exploded in to the air because they used more hydrogen peroxide than us.
