I have been a fan of Mr. Wizard, or for those of you who are too young to know who that is, Bill Nye “The Science Guy” type experiments that you can do at home for as long as I can remember. One simple experiment that I first learned about only a couple years ago was that of supercooling water and where the water is below freezing, but still in a liquid state… Then, causing it to freeze instantly. I know, sounds goofy, but simple people are easily amused I guess!
I originally posted a link on YouTube and had people tell me that it was some kind of optical illusion, or that I used a powder available in magic stores that accomplishes the same thing with non-freezing water… Go figure, the world is full of skeptics, and with good reason!
Here’s a link to a description of the actual process for those who really care… http://www.sciencebuddies.org/mentoring/project_ideas/Phys_p033.shtml
