Flying Snowball Prank [Video]
These guys came up with a pretty clever way to have a snowball fight.
So, basically they wanted people to think that they were about to get pelted with snowballs. However, this is not the case as the guys actually just use white balloons to make people think that they're holding snowballs. It's pretty funny to see the people's reactions when they think that they're about to be attacked and it turns out it's just a balloon. Most of them find it really funny, although some of them don't seem to get it.
The best is a patrolling officer who high fives the guys!
