[Mark Rober] is an uncle to three nieces and nephews, and when there is snow on the ground he faces the relentless onslaught of three elite juvenile snowball aces. Lesser men would face the fact that they are over the hill when it comes to snow-based combat, but not [Mark]. He has brought technology to his aid, and with the help of his brother created a snowball machine gun capable of firing 13 snowballs at the unruly youths in half a second.
Power for his creation comes from a leaf blower, and the gun itself is made from ABS pipe fixed onto the blower outlet. Magazines made from pipe with its top section cut away are loaded via a 45 degree junction fitting, and the rate of fire is set by how fast the operator pushes the line of snowballs with a wooden block. He has made full build instructions available as a PDF, so assuming you are reading this in a part of the world where it snows, what are you waiting for! Those of us who live in paces where it rarely snows and what snow we get is wet and slushy can only look on with envy.
The video below has the full story, complete with gratuitous destruction of fruit, youngsters cowering in their snow forts, and finally [Mark] receiving his snowy comeuppance.
