Researchers create powerful indoor hail storm.
The Insurance Institute for Business and Home Safety Research Center in Richburg, South Carolina just performed the first-ever indoor hail storm Wednesday.
Inside the massive test chamber, researchers fired 10,000 hail stones from the ceiling about 60 feet high down to a house and car. They created a four-minute hail storm. Researchers launched 1-2 inch balls of ice made of pure water and seltzer water, resembling the closest thing to actual hail. Hail stones were sent flying out of air cannons at speeds up to 74 mph.
The most damage in the hail test was to the roof with damage to the gutters as well. Researchers recommend homeowners install impact resistant roofing instead of standard roofing, which had significant dents and damage.
