Lol Go buy a rc helicopter, a large floodlight, a small amplifier, walky talkies and a set of video goggles.
Stick the floody on the bottom of the Heli, amp on next to the rotor and the goggles wherever. Fly if over your mates house at night, shine the floody and smack on the amp and yell into ur W/T's
"Come Out with your hands up!"
Scare the Sh** out of them and the rest of the neighbourhood. :D
