An anonymous reader writes "Joerg Sprave is at it again. This time, in order to bring in the New Year, he's got something with a bit more bang to it: a firecracker-launching slingshot. Being German, Joerg has built a slingshot that will accommodate the largest legal firecracker in that country. '2 grams of black powder in a tight cardboard "cigar" make a pretty loud bang! In order to make these bangs more spectacular, it is desirable to shoot them as high into the air as possible. A special slingshot crossbow has been designed, chambered for the strongest legal firecrackers. The weapon is a breech loader, and an integrated storm lighter allows the shooter to light the fuse when the weapon is all ready for the shot. The weapon launches the firecracker with tremendous force. The blunt object easily crashes through a moving card board box, and — equipped with a wooden tip — even goes in all the way into a block of ballistic gelatin.' His two videos are available on YouTube: part 1, part 2." This is the same gentleman who made a slingshot that launches machetes.
