Uphill Roller
Inspired by an article in the January 2010 issue of Home Shop Machinist I spent a couple of hours building this uphill roller, a double ended cone that rolls uphill. This has been baffling and entertaining folks since at least the late 1600s. If you want to know how it works I suggest Googling "uphill roller".
