Incredible !
The video below shows a simple disk-magnet levitating( and running like a train ) between two simple magnetic-rails.

There are various other videos showing the same thing .
It appears genuine, and is sold as a toy on Ebay, and various other sites .
For the simple disk-magnet levitating, no superconductors, or electricity, or anything else are used, just normal room-temperature permanent-magnets.
Questions :
( 1 ) - Can anyone confirm this is 100% genuine and simply what it appears to be ?
( 2 ) - You could keep that simple disk-magnet pretty still just by tilting the track( or by using magnetic-end-stoppers ), but I assume it should continue vibrating just a little, but even so, surely it should not be so easy to appear to have contravened Earnshaw's Theory ?
