Did you know about these? I didn’t until cursing around reddit (more so than usual being stuck inside). It’s a Hail Cannon. Apparently it’s useless, but it’s still pretty crazy. Basically a controlled explosion directed upwards to try and break up hail stones before they can fall to the ground. I’m not so sure how well it would work, and the research is inconclusive because the weather is, as always unpredictable.
