Winter is a great time of the year when you can tumble down friends in furry snowdrifts from the heart, ride a sleigh, ice, snowboard or ski ride and, of course, play snowballs. In the last sport, you need to have excellent dexterity in order to dodge enemy snow shells in time. But what if the attackers are too many, and victory is important to you? You need to prepare in advance and build a real machine gun from the blower leaves, shooting excellent snowballs. The American inventor Mark Robert was the first to think of this. A homemade blower store will intervene about 15 snowballs. Using air control, Mark adjusts the speed of the shells, and also changes the rate of fire: single, semi-automatic or machine-gun volley. With such an impressive weapon, not even an army of “opponents” is terrible.
