You ever duct tape cars? Shit's soooo fun. Find a good intersection or area where cars are going slow, with a good hiding place for you. Lay a strip of duct tape, about 3 feet long, across the road. Cars run it over, it sticks to their tires, and to the drive it sounds like a flat tire. They pull over 100 feet down the road and get out swearing, all pissed off, until they find out it's tape then they feel stupid.
Try it.
