This is the awesomest snow tank I've ever seen.
It was built by two guys Jonas and Sigitas in Kaunas, Lithuania. “It wasn’t really hard to build this tank,” said Jonas, “the snow was perfect and there was much of it. So we made four layers of snowballs with an empty space inside, so we could get there. Then we shaped everything with some sticks and the last thing to do was to form a main gun. We used a stick and snow for it too.”
Jonas told that idea came from the last year when they built a snow car (picture below). This year they wanted to make something more interesting.
