I heard about this amazing (but slightly scientific) practical joke and I thought I'd share it all with you: My friend Mike hass this egg timer thingy with some colored plastic beads in water with clear glass beads in it too. When you flip it over the color beads sink to the bottom but because of the glass they swirl around first and look cool. Ideally you shouldn't be able to see the glass but you kind of can. Mike and Richard figured that if they used a chemical closer to the refractive index of glass than water is, then it would be harder to see the beads and it would look cooler. So in the CRC they found this chem, carbon disulfide, which seemed like it would work so Richard went to a chem store and ordered it - the store didn't keep it in. When he picked it up the guy made some elaborate preparations with it putting it in two different safety wraps so Richard asked what the scoop was. The guy said, "Yeah, it's kind of dangerous. I mean, we don't keep it in the store." "How dangerous?" Richard asked. He looked in this guide to hazardous materials that the guy showed him and he found that there was a 10 page entry for this stuff which included: exposure to the chemical can cause sterility, impotence, damage to the peripheral and central nervous systems (leaving no nervous system untouched), its flamable and explosive, etc. A little unnerved he asked whether he could return it when he was done with it and the guy looked at him like he was crazy and said of course not. He took it home and explaned the situation to Mike and they both left it unopened on the kitchen table for a while wondering what to do with it. At work Richard had a chem friend who said he'd take it off his hands for him so without telling Mike he brought it into work and gave this chem guy the bottle but kept the box. Later that day he went home and put a glass of water in the box with a heavy piece of metal on top of it which would fall and break the glass if it was nudged. All this was in the box though, so it couldn't be seen. He then also sliced off a small corner of the box so that liquid could come out but the cut was hardly noticable. The night at dinner Richard "accidently" knocked the box over onto the floor where it obviously broke and liquid started leaking. Mike freaked out, jumped up and ran to open the door - which was locked - so he ran to his room to get the keys and noticed that Richard hadn't moved but was still sitting there shaking slightly (suppressing laughter but Mike didn't know this.) So Mike wigged out again thinking that Richard was really being affected but by this time Richard couldn't hold it in anymore and burst out laughing and had to explain the whole thing to Mike... I love this one. - Joe Devlin jdevlin@pollux.usc.edu
