Have you ever seen lab videos of a piece of ultra-chilled metal floating or spinning above a magnet?
Now THAT is magic.
You Tube has lots of videos under search term “super conducting magnets.”
One professor actually built a Mobius Strip roller coaster from magnets with a super chilled little car that zooms above (and below!) the track.
Magnetically Levitating Mice
NASA has built a device that keeps mice floating to study the health effects of spaceflight.
...a magnetic field of 17 teslas
...The researchers have shown previously that the device can levitate water-based items for hours, but were skeptical that it would be able to make a mouse, weighing10-grams, float for long periods of time. Yet, they were able to “fly” the mouse for hours, allowing it to roam freely, and giving it food and water.
