, by rotating the wheel claiming to use the power of the mind alone.
However, this "experiment" does not prove psychokinesis or other parapsychological phenomenon as hidden heat and wind sources can be used to turn it. Psychokinesis is not proven to date, while many laws of physics prohibit it as such, psychokinesis is
pseudoscientific.
History
In the 1968 psychic powers film ''
The Power'', a group of witnesses seated around a table watch a stunned telekinetic as a psi wheel turns by the application of telekinetic force by one of the characters.
Construction

There are several designs for the shape of the psi wheel, but the most common is an inverted funnel-shaped pyramid. This psi wheel shape may be constructed by creasing a small (around 2 inch by 2 inch) square of

lengthwise, height wise, and diagonally both ways, then bending the square slightly along the creases to reach the desired shape.
Another common type of psi wheel is in the shape of a cross made out of a very thin sheet of metal such as aluminum or brass. The arms of the cross are anywhere from 1.25 to 2 inches in length and up to 1/4" wide, with a small dimple in the middle so that it can be balanced on something sharp.
This wheel then balances on a sharp pointed object such as a
