Where should you go to take shelter and where should you NOT go?: If a storm is headed your way, and you learn that hail is a possibility, you should take shelter inside of a sturdy building, AWAY from windows. The reason why is because windows can break and then there's a mess of glass and hail breaking into your window. The glass can also cut you. You should NOT go, under a tree, as hail, especially the larger stones, will fall right through the tree. You also should not be outside in the open of course. You should also not be in a car to protect yourself from a hailstorm. The reason for this is the exact same reason for why you shouldn't be near windows in a house. The glass can break and then you can get hit by hailstones and get cut by glass shards inside your car. Inside of a sturdy building and AWAY from windows is the safest place to go.
The largest hailstone ever recorded: The largest hailstone ever recorded fell in Nebraska and measured near 8 inches!! That's a VERY big hailstone and would cause some major damage, that's fr sure!
How hail is caused: Hail is caused when an environment has cold air aloft, or, cold air higher up into the atmosphere. When there is cold air aloft, it is conducive to hail development. It is conducive because it helps the water droplets to freeze and actually start the hail creating process.
How big can hail get?: Well...I kind of spoiled that one, but hail can potentially get up to the size of a gallon of milk, and while that is EXTREMELY rare...if you get a good enough storm it can happen. In reality it depends on the storm you get, if you get a really strong storm, hail could be up to the size of softballs....if you get a really weak storm, hail could be pea sized. It all depends on the storm you get.
