Better than Twinkies

We've all seen the great twinkie in the microwave experiment... but have you ever done the same thing with ivory soap???  I ran across this video today. What a great idea for demonstrating physical changes!  The water in the soap turns to vapor, which allows the soap to expand.  When it cools down again, holes are left in the soap where the vapor used to be.  How fun!


  1. That is sooooo cool!!!! I can not wait to try it and show it to my 6th graders!!! AWESOME!!!

  2. I know, right? I'm going to be doing a science experiment week at home with my boys, and thought it looked like a lot of fun!
    Thanks for stopping by and leaving a comment, Leslie! :-)
