Sorry, my preference was engineering calculus and physics.  First confrontation with chemistry was at college level, I still don't understand how my classmates survived my lab experiments!

I got a passing grade though, more likely to prevent me from spending any additional time in the lab.

Thanks Page for elaboration on the chemical formula. Apparently well known by terror groups and the anti-terror units in Israel, UK and western world. Who mixed the ingredients? From general available knowledge of Triacetone triperoxide, or TATP, the investigation could NOT point a finger towards Al Qaida!

"Although made with easily obtainable ingredients, the explosive is also very unstable and will explode from contact with a cigarette or an electrical discharge. Keinan noted that Palestinian terrorists have been known to make the explosive in their own apartment buildings."
