This is an older video of a group of kids pushing a 300kg (~660-pound) tractor tire down a hill to watch it bounce and catch some serious air before cannonballing into the lake below to start a new freshwater reef. "There's no such thing." There is a such thing, that's just not what this tire is going to do. No word where the rest of the tractor went, but I doubt to go plow any fields. At least not very well.
Keep going for the whole video.
Thanks to PT, who agrees one of those kids should have volunteered to ride in it. I know at least two of my friends would have.
