I found this on a science website I sometimes visit IFLScience.com. Why do our kids just love this so much? Sometimes I get sick of explaining how it works and that it is not an experiment it is more of a demonstration, unless you are actually investigating something! In this case I think we call it an investigation. I like the article because it gives a link to the actual science behind it and lets face it, it is sorta cool! I put the link below. What do you all think? A fan of this or not a fan?
