What is the most dangerous experiment you have ever conducted?

I didn’t like working daily with gamma-radiating sodium-22, especially not when I dropped the container…

Ok, not chemistry, but involving chemicals! At university I was working on measuring droplet sizes for sprays pumped into vacuum chambers. The purpose of this was to find an ideal nozzle for a laser based plasma system. The laser we were using was a mere 4W and given its open beam and the fact that it was green made it a pretty dangerous beastie to work with. What made it doubly dangerous was the fact that the liquid we were pumping into the vacuum chamber was ethanol, and it was being injected using high pressure nitrogen that would sometimes pop the top off our ethanol canister, launching ethanol vapour into the room. Add to the danger by this being a typical university basement lab in which ventilation is something that happens somewhere else, and there we were operating a high powered laser in a room saturated with ethanol vapour, getting increasingly inebriated as time went by! Fun times.

Hahhaha OMG.
