Several times I've helped judge a science fair at the Museum of Science and Industry in Chicago with all of the city's public high schools represented. When I was a young kid I liked going to see that fair because they had interesting things like Tesla coils using a neon sign transformer and spark gap, Van de Graff generators, etc. But just as an example of how it has changed, one girl had some kind of experiment that involved a glass of water. However, she couldn't demonstrate the experiment because they weren't allowed to have anything made of glass because that would be too dangerous.![]()
