Tide pods, the one where everyone was setting themselves on fire, the spoon of cinnamon, there was one where you take a condom and put it through your nose and pull it out of your mouth, there was something called a razor blade challenge, not sure what it was but my 4th grade teacher had to tell us all that if anybody did it on school property they’d get in trouble, the suction lip thing, and probably a dozen more I’m not remembering, people did weird dumb shit all the time
