Cloudbusting

Diepersloot has installed 24 cannons on his 1,200-acre farm. At the approach of a storm, his 20ft cannons emit an electronic blast. As the sound waves travel up into the sky, they disrupt the water that is gathering to turn into hail, causing it to fall as mere rain. At least that's the theory, and an expensive one at that: Diepersloot's cannons set him back $50,000-$70,000 each.
