    Rolling uphill

    Sometimes this device is used for demonstrations in elementary physics classes...

    It's relatively easy to build one for yourself. There is a bit of mathematics involved in determining the relation between

    the cone angle
    the rail angle
    the inclination angle of the rails

    needed to make the device work...
