Secret experiments took place in Seattle on Halloween!?
Well this is incredibly creepy. If you went trick or treating in Seattle back in 1976, chances are you were part of an experiment. Apparently a woman would invite you into her house and offer you a piece of candy. She would then leave the room and someone else (HIDING BEHIND A WALL) would watch to see if you stole more candy, WHAT? This is the creepiest experiment ever. What's even weirder is that this is probably still happening, only now they can use tiny cameras. Find out more here.
