Elephant Toothpaste

We've spent time playing "Elephants" on the grass this afternoon.  It was a game that CJ made up that ultimately involved he and EMan sitting on my back as I crawled around the grass.  So as a related science experiment before dinner in the boys whining phase of the afternoon, we made Elephant Toothpaste in the sink. 
Found on Pinterest: http://preschoolpowolpackets.blogspot.com/2012/01/science-experiment-elephant-toothpaste.html They have all the instructions there, as well as the science behind it.  The short of it is this:
Mix 2 TBSP Warm Water and 1tsp yeast - let sit

 Mix 1/2 c hydrogen peroxide (I used 3%), food coloring, and dish soap (I used a water bottle)

 Dump the yeast and water into the bottle:

 Watch it foam...

 And Foam...

 and squish it all around!

 Then paint with it.

 CJ doing the American Sign Language for "Brush Teeth".  Later he was talking about it and said something along the lines of, "We made elephant toothpaste and is just keep squishing out!"  It was a fun 10 minute activity to stop the whining :)

After dinner we're heading to the drive in movies - wish us luck!  Find our 4th of July download here, and don't forget to enter the book giveaway here.
