A New Jersey vineyard owner has ended the mystery of loud booms that were shaking homes in the area.
Rob Butowski created an air cannon, the cannon made of scrap metal and the “air” from acetylene and oxygen mixing. When you mix the two gases and ignite them in the cannon, the shockwave travels about 30,000 feet up in a 1.5-mile radius.
It also makes what sounds like a sonic boom. Butowski is using the contraption to break up cloud formations and scare away birds that are eating his grapes.
Local police chief Kevin Friel says it’s all legal. “It doesn’t fire projectiles, and it’s not a firearm or an explosive. It uses gas — and that’s it.”
