I have tried to rotate an inverted psi wheel. I could rotate it. It is done the same way as
normal psi wheel.
How to make inverted psi wheel:
Take a rectangular shaped aluminum foil. bend it along the length so as to look like
a concave shape. To support the wheel, use a bulb. Since bulb is made of glass,
it has good finished/smooth surface and due to the spherical shape, it has surface of contact at a single point.
