Superconductivity Is Very Cool - Neatorama

On the 100th anniversary of the discovery of superconductivity, researchers at Tel Aviv University demonstrate how a superconductor will float in a locked position above a magnetized track.

The puck of superconducting material is able to stay locked in the air above the magnets because one of the properties of superconductivity is that that it is impervious to magnetic fields. The puck repels the magnetic field with greater force than the pull of gravity so it hangs in mid air...

Via Physics Buzz.

Addendum: The technology has now been applied to a skateboard.

Now if only there were a planet made out of either pure nitrogen or pure neodymium magnets.

It's the meissner effect. It's caused by induced fields on the surface of the superconductor cancelling out the applied field.

It figures - all those years I lived just up the road. Then I move to Florida and look what opens up! Waaah! Seriously, looks great! Maybe when I make my way back up North you will have added Weeping Angelfood Cake to the Sweeties menu ;-)

The food seems to be good guy themed. Nary a Dalek or Cyberman in sight. Guess not much hope for a Master Blaster Devils food Cake? Tell they sell franchises, guess I'll see you when the Pandorica opens.

I was hoping they'd have Banana Split or something on the Sweeties menu. Would be perfect for parties!

The Jerusalem Chicken Ceasar contains no chicken but does contain BACON, which Jews and Muslims don't eat. Strange! I would love to go there though. :)

What about "Jammy Dodgers"?
