This is another intriguing exhibit because a straight metal rod that is free to rotate about a vertical axis will be made to pass through a curved slot on a panel blocking its path. It may seem impossible at first but as the user turns the rod towards the slot on the panel, it could indeed pass cleanly through. The demonstration shows the properties of one of the conic sections called parabola, a shape which the rod traces as it passes though the slot. The exhibit also encourages the user to observe the motion of objects in three dimensions.

Hyperbolic Slot is available in the "I AM a Scientist" travelling exhibit package.
