This is the perfect prank for ruining someone`s night!
Hide these small light-activated pranksters in someone`s bedroom. When the lights are on they`re quiet but when the lights go off...that`s when the madness begins!
Instead of the victim getting some peaceful shuteye they`ll hear an irritating sound! They`ll be even more infuriated when they turn on the light and it stops!
WeÆve teamed together the buzzing mosquito and the dripping tap. This way you have back up just in case they find you out.
