Dorm & Roommate Pranks

Does your roommate keep you up at night? Next door neighbor noisy? Do you just want to teach someone a lesson and make sure they do not sleep?

Place one of these small, light-activated devices in the bedroom. When the lights go off they begin to making annoying dripping sounds or the sounds of buzzing mosquitoes. Then when your roommate turns on the light they go off! Sure to frustrate your roommate for hours trying to find the source of the sound. This will drive them insane!

Idea:
Use them when you roommate is suppose to bring home a hot date!
