so today..i was at my chemistry practical class.
the question said..
" add sodium hydroxide(NaOH) to Salt X till excess then heat it. Test the gass evovled with a red litmus paper"

so i followed...and while i was heating the substance ...


i pointed the mouth of the test tube to the short wall that divide me and the guy that sits in front of me.The wall is about 60cm high...
anyway...
heating...heating..heating...then
"POOOOOP!!!!"

the substate i was heating bursted and launched across the room!...
it showered the guy sitting in front of me and his notes..and stained the CEILING!

I had to clean the ceiling... and i apologized that guy with such a red face...

luckily...the teacher wasnt mad...and the lab assistance who is normally very mean..was laughing...

somebody shoot me
