A fellow homeschooling parent sent an email today about the proliferation of people doing the Diet Coke and Mentos experiment and posting the video on the web. I first saw this feat on Steve Spangler's blog.
Steve Spangler does science experiments on TV and has a catalog of cool and inexpensive science equipment, including the famous dipping bird. Yesterday my oldest son brought his giant solar bag to Outdoor Games Day, where it captured everyone's attention. I'm sorry I don't have a photo to show you, but if we get another I'll bring my camera next time (the bag did not survive).
I'm going to try making our own out of plastic garbage bags. I'll let you know how it works...
