I've seen countless vidoes of classroom demonstrations of NI3 decomposition and almost all of them keep the sashes open or don't even use a fume hood. It really irks me when I see science teachers not take the necessary precautions when dealing with explosives and hazardous vapors.

Cool link though diachi, very interesting project. Too bad we don't have the technology to advance it to our goal potential.

Decomposition of NI3 is Iodine vapour and Nitrogen gas. Iodine vapour isn't the best thing to breathe in.


Have a look at this.
this is a common demo on fuel air mixtures in a bottle. (woosh bottle)
A change from plastic to glass bottle caused this..

The title to the video sums that up pretty well for me. Some people shouldn't have access to chemicals. Does he think he's Joseph with that jacket or something.
