When I was in high school, I lived in high school's students hostel during the week. Bit of an army-like experience, for instance there were 8 beds in a room. Anyhow, at some point someone (one of my colleagues) stole an industrial light bulb from I've no idea where and replaced our regular 100Watt bulb in the room. I've no idea what wattage it was but probably in the 500W - 1000Watt or something. It was an experience exactly like in Seinfeld's "Chicken Roaster" episode: https://www.youtube.com/watch?v=q40fKsRsHFU https://www.youtube.com/watch?v=q40fKsRsHFU We closed the door so the warden won't see us (I dunno the word, basically the fearsome guy that was in charge of controlling some 100 restless teenagers). But light would creep out though cracks like lasers, basically everyone noticed. Anyhow (kinda stupid probably, good think we didn't get lasting damage), we would stay in the "laser" room with eyelids shut and hands over them and gradually open them and remove the hands. Eventually we got used to the extreme light although it was clearly very bright. Then we'd exit the room to the normally lit corridor and ... stumble like blind people, effectively couldn't see anything, it seemed completely dark. The whole fun lasted some 10-15 minutes until the warden caught notice and came shouting blasphemies to confiscate the corpus delicti (stolen light bulb).
