Elephant Toothpaste

25 Oct

One activity we did recently was something called Elephant toothpaste. When we initially did this project it seemed like it wasn’t going to work, then it took off and did. Mack enjoyed putting his hands in it when it came out (be forewarned that if you do this you may end up with smurf hands…well, he did as we used blue!).

[ Note to self: This will be a great project to do with him when he is older as it is a great science experiment. I certainly will need to do some research to figure out exactly what the lesson will be :)]

For this project you will need:

  • 1 t yeast
  • 2 T. warm water
  • 1/2 c. hydrogen peroxide (6% or more. I found mine at Sally’s beauty supply (20 volume clear developer). The one you find in the first-aide section of most stores is less than 6%. For more ideas on where to purchase the peroxide, visit the original site here)
  • dish soap
  • food coloring
  • 2 liter soda bottle
  • funnel
  • Tray
  • Small bowl

Dissolve yeast and warm water in the bowl.

Put bottle in middle of tray. Add hydrogen peroxide, a few squirts of dish soap, and a few drops of food coloring to bottle (after making this several times we found that adding the food coloring so that it goes down sides of the bottle, worked best for a colorful display!).

Place the funnel in the top of the bottle and pour yeast mixture into the bottle.

Remove funnel and watch the magic begin! This is a project that is sure to delight time and again!

I found the original idea on pinterest through this website.

Did you do this project? My readers and I would enjoy hearing of your experience! Share in the comments below 🙂
