Woman logic in chem lab, sorry no pictures...
Heat volatile liquids in small vial, screw cap on super tight so no vapors can escape. What? You say there is probably a lot of pressure in my vial, I might as well open it right now and check.
That actually happened yesterday, after the TA told us specifically not to tighten the cap all the way. It shot out hot vapors and the girl that was standing in front of me took the hit. It was on her arm and she sprinted to the sink to wash it off, so it must have burnt her a bit. Thankfully i was only a 20ml vial and not like a ton of vapors. Thats more stupidity then woman logic... But according to this thread they're often one in the same.
