title: Electrostatic Floating Ring
aka:   Magic wand

A loop of light packing sheet is taped into a ring and charged by rubbing with fur or dry skin.
A "golf tube" made of polyethylene is similarly rubbed.   The ring can be floated above the tube.


    Would this work on the moon? (ie. with lower gravity and in a vacuum?)

     Can you be called "Lord of the Ring?"
