30 Days to Hands on Play: Concoctions: Elephant Toothpaste...Sort Of

Day 10 of the 30 Days to Hands On Play challenge brought excitement to my little world.  The challenge was Concoctions, and boy, did I know what I wanted to do with my kids....Elephant Toothpaste!  If you've never seen Elephant Toothpaste then check out this video:

I checked my ingredient list and found I had everything...except the beauty supply bottle of hydrogen peroxide...but regular ol' hydrogen peroxide should work...right?

According to the video we needed hydrogen peroxide (HP from now on), dish soap, warm water, yeast, and food coloring.  I was thrilled to find we had an empty soda bottle in the garage as we hardly buy the stuff.
 Ariel pours the HP into the empty soda bottle.  
 Michael adds the dish soap.  
 I mixed the yeast with the warm water.  It became a bit pasty.    

Then we added the yeast mixture to the HP mixture.  Here's how it goes....*spoiler alert* it's a dud!

We waited...and waited...and waited...then we gave up.
 But the kids were able to play in the bit of foam we created.  
 They felt it, splashed it, and practically took a bath in it.  
 And Michael, being the tool man he is, experimented with the funnel.  

What we learned:
  • Regular HP is only about 3%.  Beauty Supply HP has a higher concentration, at least 6%.  The higher the concentration, the better the reaction.  You can purchase 8% from Amazon!    
  • If at first you don't succeed....we'll be trying this one again!

  3. Thanks for sharing this! Just today, I was wondering if I could get away with using regular hydrogen peroxide and then decided to just do something else! :)
