Dylan had a funny post about azides and their danger. It really seems like labs that use azides explode all the time. That’s why I’m a p-chemist: just don’t shoot the laser in your eye and you’ll be fine.
But the all-time winner of the stupid-stuff-to-do-in-lab award goes to the infamous quote above from Merer, A. J.; Mulliken, R. S. Ultraviolet Spectra and Excited States of Ethylene and its Alkyl Derivatives. Chem. Rev. 1969, 69, 639–656.
Quote: “Evans boldly put 50 atm of ethylene (C2H4, trans-C2H2D2, or C2D4) in a cell with 25 atm of O2. The apparatus subsequently blew up, but luckily not before he had obtained the spectra shown in Figure 8.”
