Boom! One man's attempt to control the weather.

Personal hail cannons. Yup. You know this will lead to trouble.

"I believe in WWI or WWII they were seeing them in the war when the Howitzers were shooting up at each other. And when they were shooting there was no hail,” he says.

These days, China's using howitzer-like artillery shells filled with chemicals to seed clouds and make it rain. But John wants to turn destructive hail into a gentle rain with a hail cannon.

"What comes out of the top of this thing? It's a vibrational sonic boom,” he says. "When it hits the clouds it's a little bit of vibration doesn't allow the ice to form.”

John and about four other area farmers have spent over a $1 million on 18 of these cannons collectively when hail insurance got too expensive. " LINK
