It ' s pretty crazy how unregulated high school or younger science labs can be given the equipment that is available . I was a lab aide at my shitty super small private high school , basically just setting up all the chemistry experiments during my study halls . I wasn ' t in college yet , so I still liked chemistry . The chemical storage closet had so many interesting things that were never used at all for any class or experiment . The building was about 80 years old , so I have no idea how long half of the stuff had been sitting there . Naturally , my friends and I made use of what wasn ' t needed . First , we found this one acid that was stupid high molarity and kept in a fucking Russian nested egg of containers to keep out any and everything . It destroyed all challengers books , # 2 pencils , sheets of metal , a padlock , some stones . I can ' t tell you how much fun we had melting shit . Then there was the sodium . What looked like a 1950 ' s coffee can filled with solid sodium submerged in this gelatin stuff . We didn ' t really believe it was what it said because the containers weren ' t in very good condition and surely that would be too dangerous a situation for a school to overlook . well we launched it into a pond and yea , it was definitely some kind of alkali . But the best thing we found was the electromagnet . It had to have been 50 years old , but my god , it was a beast . We would pull stools across the lab and toss metal balls to each other knowing how they would be curved by the magnet , like some Wanted bullet curving shit . We never turned it up all the way because we were worried about the gas lines on the tables . If you want a relatively cheap form of entertainment , get the strongest magnet you can afford and just pull shit with it . Then I turned the keys back over and graduated . Pretty sure no one will ever notice anything is gone , or even knew it was there to begin with .
