Explosives Camp
theodp writes "How about a summer camp where you get in trouble for not blowing things up? Students with a passion for all things explosive and proof of US citizenship pay a $450 fee to attend Summer Explosives Camp, 'We try to give them an absolute smorgasbord of explosives,' quipped a professor at the University of Missouri-Rolla, which offers a minor in explosives engineering. Here's the brochure (PDF), kids!"
So we should deprive kids of safety and proper handling knowledge just in case they decide to turn on us right? Unlicensed? How do you think you get licensed, magic? They get licensed by receiving the proper training and various checks... which is exactly what this is... atleast in introductory fashion.
If those 'kids' got a little 'inspiration' they could find far more dangerous information in a public library. I've got an old chemistry book from 1902, copies or similar books are no doubt common. That book reads like a Betty Crocker cookbook. I'd much rather interested kids receive real training and experience than try some of the stuff they could cook up on their own.
