If you’re looking for a great Christmas gift for the “scientist” at your house, check out Elizabeth’s Discovery Exclusive Tornado Lab. And for the non-scientific students, it would be so much fun that they wouldn’t know they were learning. When I used to teach first grade, we would do a science experiment with a two liter bottle and make our own twisters. Sometimes it worked and sometimes it didn’t work very well. This would have been so cool to have!
