      Me too, We have a long list of ice experiments we can’t wait to try!

  1. You can find film canisters here, if you want to order a bunch for a kids’ party or educational activity: Film Canisters:

    I also have an iPhone, iPodTouch app, http://kidscienceapp.com that’s full of fun ideas for science using what you have on hand. My first book, Kitchen Science Lab for Kids, will be out in August and is available for pre-order at all the major online book retailers!

    Thanks for sharing one of my experiments!

    1. Lemon Lime Adventures

      Fantastic! Thank you!

  2. FYI, I’m in no way affiliated with the film canister seller. I found them when I was looking for a place to buy them for people who don’t have a film store nearby.

  28. Thanks for your wonderful ideas about projects with ice and fizz to teach kids about science. I wish my kids could think learning about this subject was fun in school too. My husband and I are looking into elementary school STEM assemblies for him so that he can start to love learning about science.
