/sci/ - Science & Math

What's your worst lab incident, /sci/?

I'll go first:

>be me last year
>spergy amateur chemist
>be interested with synthesis of nitrous oxide
>parents go away for weekend, have to stay at grandpa's
>convince grandpa to take to house to do homework
>decompose molten ammonium nitrate in garage instead when gp leaves
>be on third trial run
>caking agent used to hold shitty ice pack NH4NO3 together causes insane foaming in reaction flask
>decrease hot plate temperature
>suckback from loss of pressure pulls water from scrubber into flask with molten ammonium nitrate
>foam spills into rubber hose leading to scrubber flask
>forget that foam is liquid ammonium nitrate
>pressure blows stopper off the reaction flask
>liquid NH4NO3 sprays all over the garage
>sweet smelling smoke fills room
>ohshit.jpg
>try to throw paper towels with cold water onto hot plate
>catches fire
>throw them on concrete garage floor and let them burn out
>smoke filling entire front part of house
>step outside to catch breath
>clean up as if nothing happened 30 minutes later
>explain to dad that the small white stalagtites on ceiling are from splashed saturated solution of NH4Cl weeks later

mfw almost burned down my neighborhood in the name of chemistry
