Device demonstrating hyperbolic function

User tries to move straight edge through the hyperbolic cut.

On the base plate, there is a metal frame structure. One arm of the vertical structure carries a rotating hyperboloid rod. In the design plexiglass with a slot, there is an opening. The hyperbolic section shows the mathematical aspect. Hyperboloid bar, although it is flat, with ease passes through the opening in a curved plastic (it is tilted).
