<Hurley> Dude, This is the ultimate Halloween prank. </Hurley> http://slashdot.org/comments.pl?sid=42736&cid=4486745 In only a few hours, I will be helping in the construction of one of these! We already have all of the materials. A fog chiller like this will work almost as well as a professional one. The professional fog coolers essentially blow the fog through an refrigerator evaporator. Halloween of 1994, I had the police at my house 6 times, each time with them begging me to stop doing what I was doing... he so badly wanted a reason to arrest me, but could think of none. Picture it: The doorbell was connected through an optocoupler to my computer's keyboard. Everytime the doorbell rang, there was a pause (as the stereo audio file loaded) then a loud scream played from a speaker (left) hidden in the trunk of one of the cars in the driveway. The right channel had a nasty kind of chewing sound, and it was played through a speaker hidden in the engine compartment of another car which was parked close to the door. My roommate and I were car nuts, and we had a junked Toyota that we were waiting for the scrapyard to haul off. With the chain hoist, we put it on its side in the front yard, with a mannequin's arm sticking out from underneath. We hooked its electrical system up to a car battery charger and left some of the parking lights on, with a turnblinker flashing and the AM radio playing quietly inside. I was working in the professional sound and lighting business then, so I borrowed a fog machine, fog chiller and 6,000 watts of Leko stagelighting. The fog machine and the chiller from work went outside to provide a ground mist, but not too much. I needed for the kids to see, by the light of the flashing signal, the arm sticking out from under the Toyota. The Lekos and my own fog machine were set up inside. The Leko dimmer pack was powered off the 40 amp 240V service to the stove outlet, and all 6 lights, at 1000W apiece, were pointed and focused to a point 1 foot outside of my front door. And then there was the chainsaw. Beg, borrow, steal or rent a chainsaw. Take off the chain and protect the kids from the potentially sharp edge of the chain guide with a rubber edging like people use around the outlines of their car doors. The Spectacle: Mom or Dad would stand at the end of the driveway as Little Tommy would walk past the Toyota with the flashing lights and the arm poking out of the ground mist. Little Tommy, dressed in his finest Teenage Mutant Ninja Turtles costume would press the doorbell. He'd hear the ring of the bell, then a couple of seconds later, the scream from the trunk of one of the cars he'd just passed. Gradually, he'd become aware of a wet chewing sound right behind him. If Little Tommy was still standing at the door by the time I got downstairs, he'd be greeted to the sound of the door opening, and a wall of fog in front of him; invisible foggy blackness. Of course, wearing black and a black ski mask, I'd be standing there watching the look of fear on the kid's face as it flashed on and off in time with the doomed Toyota's right turn. And then, just when we thought Tommy was getting ready to leave, Mike would kick the foot-pedal that turned on all 6kW of stagelights, focused right at the kid's face. Blinded and disoriented, Little Tommy would start to retreat as I started up the chainsaw. And his first sight of me would be the silhouette, through the fog, of a black shadow with a running gas chainsaw. Frozen, the kid would stand there, a deer caught in the headlights, as the chainsaw-wielding black shadow pressed the blade of the saw to his neck and revved the motor. Of course at this point, the parent, standing at the end of the driveway, would feel that Little Tommy was in mortal danger, scream, drop the bag of candy, and attempt to rescue him from the chainsaw which would have already taken off the kid's head if it still had a chain. The next morning, I had 4 broken windows, hate messages spray-painted onto the side of my roommate's car, the smell of two-cycle oil in my living room, and a hell of a lot of toilet paper and broken eggs to clean up. But I only had to give out 1/2 bag of candies, so I think I did okay.
