That's kind of how we got LSD, saccharin and microwave ovens. (not really "playing with" but not being super careful about safety)

Even when the play is "touching" and the chemicals are "food dyes"? I wouldn't say I'm a risk taker, but even I would probably try that out for giggles.

Even if not intentional, such things happen by accident. Have you ever read up on how the psychedelic properties of LSD were discovered?

I did, as a kid. Blew up the kitchen. Got good at home chemistry.

Still do at times, but it's much harder to get the good stuff, like KNO3.

Clearly you don’t know many chemists? You might as well tell EOD to not play with explosives!

confirmed as correct

> You don't play with chemicals

How else do you learn?
