One of the sneakiest disruptive frustrating kits ever made. This is just the ticket for a curious friend who just can't resist picking up this innocent looking creation. As soon as he or she picks it up it emits an obnoxious noise which can't be silencedyou can't turn it off with the switch and the way it is constructed you can't even remove the battery! Once they pick it up they have really messed up that is unless someone knows the one secret turn off procedure!
