I wouldn't mind getting my hands on some thioacetone to play with. Oh the deviant things that could be done with something like that! I wonder if it's one of those obscure drugs that haven't been made illegal to yet...

"One eye witnesses describe the event simply as:

Автор MyImmaculateQueen ( назад)
Your video is weak. Does us all a favour and talk about something relevant.
Here are 2 poisons we should all avoid
1. MERCURY - it's a neurotoxic poison contained in many vaccines.
2. FLUORDIE - it's in our water supply and causes more cancer than any other chemical. Dr Dean Burke PHD and 34 years at the National Cancer Institute.

I can see from the quality of the writing in these comments that you are very intelligent young people.
Here's something you may find interesting: Nuclear reactors tend to blow up because the fuel rods cans are coated in Zirconium, which when heated to a certain point starts catalytically producing Hydrogen in large amounts from the reactor's cooling water... Do you see the connection and why it's so important you do?

Azidoazide Azide is a nice name. You can't admire it though, it'll just explode.

That's just a heap of Fluoroantimonic Acid
YouTube even says it's spelled wrong, thats how unpopular it is.

thioacetone + timed release mechanisms= surefire way to demoralize isis. unfortunately this is chemical warfare so it's banned, but i can't help but giggle at the thought of stinkbombing terrorists into submission
