The thing about snowballs is that the shape doesn't matter so much as the density. That makes this Sno-baller, a scissoring snowball scooper, a bit suspect. I can't imagine that you'd be able to pack them down as tightly as you'd want for the to retain their shape in air (but still explode in a cloud when they hit your target).
It's only $9, but you can buy a lot of snow for $9. Anyone used one? I'll willing to believe these could work, even if they do seem ridiculous.
