Snowball Sling

I and my sons were out playin' in the snow Christmas afternoon. Sledding down the back yard and chuckin' snow balls.
We discovered that a giant waterballoon sling-shot can fling a snowball at an alarming rate of speed for an amazing distance...
Joe is going to bring one back to school with him. Plenty of snow in Upstate NY. He plans to ambush his fellow classmates from
the balcony of his dorm building. Cool. (Literally...)
