hi
I was wondering, if any of you out there could help me come up with some designs for a snowball launcher (one that is efficient, and safe).

the reasonn why:
A bunch of my friends and i are having a big snowball fight new years eve. Some of them think that I wont be a challenge because i am a nerd/geek/dork. I wish to prove that geeks arent to be underestimated

Any help you coud give me would be appreciated. Thanks

I already have the basic slingshot design, I was hoping for something a little more advanced/ creative/ precise
