chem lects.. again
this time round, as it was my lecturer's last lect with us, he bade farewell to us in a very interesting fashion - he held a demonstration at the end of the lecture, but boy was that interesting..
he first mentioned about semtex to us - basically it's a mixture of explosives lah, nasty stuff indeed.. but he produced cotton balls dipped presumably in semtex, and started to explode them by bringing a hot rod close to the cotton balls.. what happened was that the cotton balls disappeared - poof! - in a ball of flames.. the lecturer casually mentioned that the explosion was "neat" because "it didn't leave any residue behind".. hmmm
he then tried exploding it on HIS HAND.. chao gung ho la.. thank goodness his hand wasn't blown to bits cos the reaction was too fast to immolate the palm holding that piece of cotton ball..
he then produced a sheep - made from cotton, mind you - and then said that it was the "pride of the lab technician".. he then used a loooooooong pole with a metal rod stuck to its end, and started to heat the rod with the bunsen flame burning merrily nearby..
and then, he brought it near to the sheep..
and the entire thing exploded like a fireball! i was sitting 9 rows away from the demonstration, and i could feel a wave of heat washing over my face when the sheep exploded! it was soooo cool!! what was left of the sheep was only the metal frame holding it in shape =) i shld have brought a camera to the demonstration, dammit..
see why i'm inspired to continue taking chem next year? =D
