Answer 2

Just as mokh said, you can make snow blocks.

cool things about snowballs: If your riding a pig and you throw a snowball at the pig your riding on, it is possible to 'fly' with it, but it is difficult.

Snow golems are going to be in 1.9 (pre release is out) and they throw snowballs at hostile mobs! Though this does 0 damage, it is fun to watch. A snow golem drops snowballs at death.

Snowballs can also be use to hit someone into a pit.

A ghast fires a burning snowball but this will be changed in 1.9

also wolves take damage when hit with a snowball.
