    We used to make these all the time as kids. You need a second pair of magnets in push configuration on the back for this to work.

        With the right electric field you can generate (a small amount of) thrust our of ions in air flowing over a charged plane.

        One of the myth-busters “anti-gravity” devices they tested was actually (very weak) a static electric ion thruster.

        Pretty cool - but it did need electric power input.
