make what you see in the picture. look at the edge of the steering wheel looking minetracks and spam the right-click (with a minecart) and wait for a million to pile up, spinning on it. then pull the lever connected to one fourth of the steering wheel tracks, and the minecarts will transfer to the long minetrack and fly off, and they will go forever, without a minetrack underneath. you can even ride it! its a great fun glitch!
