My unusual collection

the smell test - reminds me of a guy i did my chem with back in the day...

he was a great guy and absolutely brilliant in the mind (compared to my distincly unbrilliant one) but had often had momentry lapses of realisation of the real world.

so for example, in one prac session he had conical flask which he had to swill around for 60 seconds... he is busy swilling and decides that he should check his watch to see if 60 seconds has elapsed... he turns his arm to see his watch... and tips the product on the floor.

another day he managed to get a mouth full of hypochlorite solution whilst drawing a pipette


smells in the classroom are great too! i had a particularly uncoleagial coleague who's class was in the room i used immediately after me. when she annoyed me sufficiently i used to leave unpleasent smells in the sink down the back of the room which would cause consternation amung her students who would disrupt the whole lesson. n-butyric acic, which smells like off cheese, or burnt milk (you get the idea) was a bit of a favourite, but i didnt mind stashing a little lump of FeS in H2SO4 up in a cupboard somewhere... the ultimate 'fart' smell.

ah, the memories come flooding back :biggrin: and who could ever forget when i put the goldfish from the science lab in her coffee cup in staff room, or liquid nitrogen in her lunch box whilst she ducked off to the toilet?

Guilty of this tooo.... though now I don't remember what the liquid was!! hahahaha

Also spilt some sodium hydroxide on my black jeans... haha.. suffice to say I could never wear it again!
 
As someone who lost a patch of hair to a small chem lab explosion, I find this thread rather disturbing.

Never cork a test tube while it is still reacting.
 
one should always have a healthy respect for chemicals.. even simple household chemicals can be nasty if used in ways not intended by the manufacturer.
