> Now, the exciting chemicals in classic chemistry sets are illegal.

As a safety professional, I find this a rather odd statement, as there are very few chemicals out there that are illegal to buy and sell. I wonder if the chemical educators on the list can provide examples of such chemicals that are illegal to use? (I'd also be interested in the definition of "exciting" in the chemical education context.)

Also, I posted a note recently about the Chemical Heritage Foundation's iPad version of a chemistry set (see https://itunes.apple.com/us/app/chemcrafter/id839552862?mt=8 ). I had a chance to play with it over the weekend and while the splash screen says "Safe for All Ages", I'm not sure I'd want a 10 year old to use the game as inspiration for things to try at home, such as seeing whether copper really does react with nitric acid to produce that interesting brown gas (nitrogen dioxide).

Thanks for sharing this.
