What’s Under the Bed?
When I was a kid, I got the Sabrina the Teenage Witch “Handbook.” It was full of kiddie experiments and stuff, and it was pretty fun. My older sister had upset or annoyed me about something, so I tried out one of the “tricks” from the book. You fill a cup with water and some corn kernels, and put some tinfoil on top of the cup. It worked too well.
The kernels eventually pop and it makes noise against the tinfoil, but it takes a few days to “work.” I put it right under her bed and then I completely forgot about it….until one night I woke up to my two sisters screaming like crazy. It had popped in the middle of the night and she thought there was a rat under her bed.
