So true story now, there was this Russian chemist, I can’t remember his name, but he was chewing gum in his lab and he used to dip his gum in a flask containing citric acid to give it a bit of a kick, but one day he had another flask that had white crystals in it that looked like citric acid, but when he dipped his gum in and started chewing it his face exploded because it was actually some Russian explosive chemical or something.
