The tactical world can be a fun place. But when you take the art of crafting a tactical weapon and bring it to a snowball fight, that’s when it gets really fun.

Mark Rober, of Creativity Design Science, was sick of being ganged up on by his nephews and nieces in snowball fights, so he did what any logical thinker would do: He designed the first ever snowball machine gun.

With the help of his brother, Brian, Mark took a leaf blower, equipped it with a plastic feeder for the snowballs, and quickly had his snowball machine gun.

Mark was able to control the speed of the snowball machine gun, which at top speed shot off 13 snowballs in just half-a-second.
