Researchers for the Insurance Institute for Business & Home Safety have created an indoor hailstorm. The artificial hailstorm experiment is being used to test the impact of different hailstone sizes on different types of roofing material.
Engineers designed and built multi-barreled hail cannons for the experiment. The cannons are mounted on the research center catwalk and placed 60 feet above the test house. The cannons can deliver approximately 8,000 to 10,000 hailstones.
