My High School fraternity's faculty sponsor was the biology teacher, Fr. Mike, who had access to lots of surplus stuff (for example, the X-Ray textbook with an X-Ray of some guy with a standard-sized Heinz Ketchup bottle up his rectum; he had originally claimed he was mugged but it was later determined that he'd done it himself, according to the text).
Things were different back in those days ...
For initiation, the fraterntiy had three electrified items, each hooked up to its own battery and Model T ignition coil: a rug with interlacing electrodes, a chair with an array of bolts in the seat, and a real coffin with interlacing electrodes in the bed.
The chair was used as a lie detector:
INQUISITOR: What's your name?
PLEDGE: "..." (It didn't matter what your name was ...)
INQUISITOR: WRONG! ZAP! (as they came flying out of the chair)
One had to walk across the rug, and lay in the coffin, with similar results. They stopped putting the lid on the coffen a few years before when a football player with claustrophobia came through the lid when he was zapped, putting a crack in the lid, and then ran out the gym door and down the road in his socks and gym shorts.
Then there were the pills Fr. Mike got from a pharmeceutical rep friend that were used to dye ones urine to check kidney and bladder function. There was always one guy who couldn't swallow a capsule and ended up chewing it and getting blue dye all over his mouth and face. They had stopped using the red dye when some kid peed at home and his parents became concerned.
Reminds me of the story in which the police were interrogating a known criminal at the police station. They used a photo copier as a "lie detector" - when the thug answered a question, they would hit the copy button and out would come a piece of paper with the words "He's lying" printed on it.
The thug was not too bright and actually believed the copier was a lie detecting machine. He eventually confessed.
When I was in third grade I "invented " a shock machine. It was a small cardboard carton, about 1x2x3 inches, that had two leads with ring terminals on the ends. IT was called the shock box, which was quite amazing since inside the two wires were simply tied in knots so that they would not pull out. But then result was just as effective as if it had been a powerful shocking device. Of course the school authorities didn't take to it very well, but when it was opened for examination they realized it was harmless. But the fact that something could be believed with absolutely nothing to back it up is still amazing.
When I was in High School back in the 60's I got a plastic box and mounted a 10 microamp meter on the front. Inside the box I had a 9-volt battery in series with the meter connected to two screws with their heads exposed on the bsck cover of the box. I printed an official-looking "Marijuana Detector" label and put it on the front. I could wet my fingers and then when I pressed against the screw heads I could make the meter go up and down. It was fun to walk down a row of lockers as if the device was "sniffing" for drugs. I had some upperclassmen sweating bullets.
My Dad was in charge of Security and Safety for a grocery store chain at the time. When he found out about the device he asked if he could take it to work. He came home that afternoon laughing. It seems that he had pulled the prank in one of the stores. When he got close to one of the lockers an employee approached him and asked if he could resign without any further questions being asked. I guess the device really did detect marijuana after all!
David - He moved away the summer before high school so I lost track of him. He was back in town very briefly a few years later with some stories about both breaking into the school computer and helping administer it where he had been living. But I have no idea after that.
