I still remember the lid blowing off a coffee tin fueled by a custard powder - air explosionCareful what you teach! You might get arrested. Quote Share this post Link to post Share on other sites

Times have changed - we had a teacher in HS show us how to blow up a 2 litre bottle using aluminum foil and a solvent found at the hardware store.

I didn't learn anything like that in chemistry class in HS, we had other manuals that taught us a lot about IEDs as well as a former Vietnam SOG person that we had befriended as well. So aparently times changed before I was in high school as well (even though I graduated high school pretty recently...1998).--"When I die, may I be surrounded by scattered chrome and burning gasoline."

AndyMan 7 #7 February 16, 2005 I imagine its only a matter of time before a teacher gets arrested for telling students what happens if you combine two popular cleaning supplies: chlorine bleach and ammonia. Hint: Don't try it. Teaching kids the basics of what will kill them is a good thing. _Am__ You put the fun in "funnel" - craichead. Quote Share this post Link to post Share on other sites

The stuff at Walmart works pretty good, trust me on that one. I believe the reaction also produces a rather flammable gas as well.

dropoutdave 0 #12 February 16, 2005 I don't buy the whole "times have changed" thing. My Dad has told me countless stories of him and his friends blowing shit up. He even got the cane for setting fire to his desk in class. Sure things may have changed as far as chemicals go but kids were still kids back then. One of his finest moments was when he and a friend took one of those 5 foot tall gas bottles about 500m out to sea when the tide was out and put a blow torch on it and ran. It took quite a while for it to blow but when it did it was one hell of a bang. Left a hole the size of a bungalow apparently but I think he might have exaggerated that a bit to big himself up. Blame the parents if anyone, I sometimes wonder why I like to blow shit up and make potato cannons. hehe ------------------------------------------------------ May Contain Nut traces......

(true story) Actually it produces chloramine gases, which can them form hypochlorous acid, ammonia gas, and nascent oxygen... Stuff you don't want anywhere near your lungs.

happythoughts 0 #14 February 16, 2005 When I was in high school, our chem teacher tossed some potassium (I believe) into a beaker of water and it exploded - in class. He also burned some magnesium. We learned how to make slow burning gunpowder and make stink bombs with sulfur. Quote Share this post Link to post Share on other sites
kallend 2,175 #15 February 16, 2005 I went to school in the '60s and studied science. Sometimes I wonder how we survived. I recall making mercury fulminate in the kitchen! Skydiving seems tame by comparison.... The only sure way to survive a canopy collision is not to have one. Quote Share this post Link to post Share on other sites

My grandmother used to teach in highschool. One year they had a student who thought it would be a great idea to swipe some potassium from the chem lab, he did - and put it in his pants pocket on a hot and sweaty day. You can put that on the list of things that didn't go so well. - Jim"Like" - The modern day comma Good bye, my friends. You are missed. Quote Share this post Link to post Share on other sites

mr2mk1g 10 #21 February 17, 2005 I swear I'd have a US "bird" permanently over my parents place if I was a teenager today... I used to make a nice bit of money ratting for local farmers. Best way to do it was stick a couple of fire bombs down their holes and stand back with a shotgun and my lurcher. Icing sugar and weed killer (with as high a content of potassium nitrate as you could find... given I was doing this for commercial farmers I could lay my hands on some pretty potent stuff) wrapped up in some newspaper. Very simple fuel and oxidant bomb... would shoot green flames 10ft out of the rat hole you stuffed it down and smaller flames out of all the other holes you hadn't yet found. Sublimely simple - the fire simply followed the tunnels; anything that got out alive would be finished by me or my dog. And that was just for pocket money... for fun I built a mortar tube and experimented with different kinds of warheads. Living in the country was far more fun than a city, I'm sure. Still - different times... and this was only a dozen years ago or so. Quote Share this post Link to post Share on other sites
Fast 0 #22 February 18, 2005 My chem teacher did the basic Ka, Na, metals in water stuff. Mg burning, etc. He also demonstrated the differences in reactions based on having the right quantity of a compound available. Think: H2 in balloons compared to (2 part) H2 (1 part) O2 in balloons. Was a fun one to watch... He also made a mild contact explosive. He showed us the formula but not how to make it. Problem was most of us were smart enough to know how to make a compound from a formula using simple reactions based on the fact that they were teaching us that stuff.

krouton01 0 #23 February 19, 2005 Wow this is pretty ridiculous that your standing up for this guy. I'm for protecting our teachers from undue prosecution but this is just stupid. he taught kids how to make bombs. This wasnt a simple chem explosion either. He brought in videos of him and his friends making quite deadly bombs. He was warned repeatedly not to bring the video. The children then with info they gleaned from there teacher used the bombs not once but twice to blow up someones private property. While the kids should take responsibility for there action a teacher has to be somewhat mindful of the information he so cavilerly dishes out. Quote Share this post Link to post Share on other sites

EBSB52 0 #25 February 20, 2005 I wonder why they could teach this stuff 20 and 30 years ago but not now? Are our kids more depraved? Is the old cop out, "the sign of the times" crap perhaps? Or is it that society has become so greedy and anti-social that people realize that getting ahead is not realistic, so they turn to desperate measures? Funny how we continue to attempt to fix the problem by throwing bandaids at the symptoms. Quote Share this post Link to post Share on other sites
