I would start the same way my high school chemistry teacher did when she said. "sometimes science isn't safe". My uncle's childhood chemistry set had radium in it. There are a lot more of us than there were back then, it is ok if some of us die in the pursuit of knowledge. It is a worthy goal, in that people like Curie paved a way to a better standard of living for the rest of us. If you can't demonstrate any cool experiments how are you going to attract future chemists? A different uncle who actually became a chemist had a crc reference that made your fingers itch just to turn the pages. I'm half convinced it would qualify as a superfund site and it was just a reference book. We worry too much about the wrong things. I'm sure all the big pharma in the water supply is fine, but chocolate has way too much cadmium!
