If you're looking for a new way to guarantee winning in your next snowball fight, you can't get better than this.
Mark Rober's self-created snowball machine gun can fire 13 snowballs in 0.5 seconds, which is a decimating amount of snow to be hit with in such a small time period and would probably make the opposition surrender immediately.
All it takes is a leaf blower, some tubing, a lot of snow and a hankering for some DIY to create the snowball fight WMD. Although, with the amount of snow we get here it's probably too much work for very little reward. Unless you live in the mountains. In that case by all means fire away.
