Hello I have homeless going through my vehicle breaking windows, drilling holes in my gas tank, the list goes on... I have the desire to trigger some kind of device in the car to release fart spray when they enter and I wanna put it on YouTube. The problem is when I search remote triggers online there are only expensive kinds that I wouldn't want to risk to the bum walking off with. Is there any type of trigger I can rig to go off to a specific frequency that's like dirt cheap? I want to trigger a rocket engine ignitor that will burn a string releasing a hammer that will crush the fart liquid ampule preferably somewhere the bum can see possibly above the seat so the liquid drips on him hahaha
