Hail cannon
Shock wave generator meant to prevent hail
A hail cannon is a shock wave generator claimed to disrupt the formation of hailstones in the atmosphere. These devices frequently engender conflict between farmers and neighbors when used, because they are loudly and repeatedly fired every 1 to 10 seconds while a storm is approaching and until it has passed through the area, yet there is no scientific evidence for their effectiveness.
