hail can become biger by the winds carrying up water droplets back into the sky and freazing it over and over again. Hail can become bigger by the winds carrying up water droplets back into the cloud and freazing it , then doing it over.

Updrafts within thunderstorms push rain high into the cloud where very cold air freezes it. Once frozen it starts to fall but gets caught in another strong updraft where it gathers more moisture on its way back up making it larger. If the updrafts are strong enough they will continue this process for long periods of time allowing the hail to accumulate more moisture and more moisture. In a severe thunderstorm downdrafts may act like a wedge and increase the intensity of the updraft. Updrafts can get so strong they even intrude into the stable stratosphere. When updrafts are this strong it becomes possible to suspend large hail for long periods of time further adding moisture to the hail, sometimes building it to incredible sizes. Updraft winds can be from 100 to 120 miles per hour when producing Baseball and larger size hail.

Hail becomes heavy because the colder a thing becomes, usually the denser and heavier it becomes as the atoms that make it up start moving closer to one another.

On the other hand, however, in the case of water, this effect is limited around freezing point (Hail is frozen water). Nevertheless, it has already become denser by that point and is therefore, heavier than when it was [say] 10 degrees Centigrade.

Hail stones are balls of ice- and can be very heavy- some are 2-3 pounds. They are formed high in storm clouds, and when winds will no longer keep them in the air- they drop. A heavy weight, falling a long way (thousands of feet) so they may be traveling at 200 mph when they hit. Yeah- that's gonna leave a mark...
