Sidney was napping so we decided to do a little science experiment & make "Elephant Toothpaste"
We started with a baking sheet & an empty water bottle.
Here they are ready for action!
1st: mix 2 Tbsp warm water with 1 tsp yeast in a seperate container.
2nd: into the water bottle we poured 1/2 cup 6% hydrogen peroxide (mine was 3% - I think if I had 6% it would have been "toothpastier" lol) 4-5 drops of food coloring & a squirt of dish soap.
3rd: we poured the yeast mixture into the hydrogen peroxide mixture.
Then we watched in amazement as the mixtures reacted!
The toothpaste flowed out onto the cookie sheet.
Our first round was green, so of course we had to do a 2nd round with BLUE!
Then we had to play in the "toothpaste".
Our experiment was a success & we shall do it again some other time when we need some entertainment!
I found the idea through Pinterest & got the info from this blog:
And the details of the reaction if you want to know:
quoted from the above website!
"The reaction is summarized by this formula: 2 H2O2
--> 2 H2O + 02.
Hydrogen peroxide (H2O2) naturally breaks down into water and oxygen. It is stored in opaque containers to help slow down this process. Catalase (an enzyme in all living things, including yeast) speeds up the reaction. Dish soap catches the oxygen and makes bigger bubbles and the food coloring makes it look cool. The foam and bottle feel warm because the reaction is exothermic--it releases energy as heat."
