You can use it to surf through the solar system. Just don't put it in your mouth

You don't need a rockets or thrusters to travel through space. All you need is a giant, electrically-charged carbon-fibre stocking that surfs planetary magnetic fields.

From New Scientist article:

A cylindrical mesh of fibres – resembling a stocking – could also be attached to the spacecraft. To charge itself up, the stocking could be coated with a radioisotope, and one of the most powerful would be polonium-210, the isotope used to poison former Russian spy Alexander Litvinenko. But it should be safe to use on the stocking "as long as people working on the spacecraft don't lick it".

This idea is only on the drawing board at NASA's Institute for Advanced Concepts. It will probably be a few years before we'll see giant radioactive stockings in our skies.

I can't wait.
