No tricks though, right. Watch how the tires roll uphill, bump into the next one, and start rolling uphill, again.
Cool video for sure.
It would be posible to make that happen. Just put some weight in the tire and set it so that it is at the top. Then when it gets nudged, it will roll the tire uphill.
I'm sure there had to be some tricks involved. Great ideas though
