Neat!
Magnetic oxygen defies gravity, and drips up.

Kinda cool, I guess, but ferrous metals defy gravity the same way by being pulled up to a magnet just overhead all the time.

but is it really defying gravity, or being acted on my a force that is stronger than gravity.

"Discovered"? It's just paramagnetism... There was a picture of it on the cover of my chemistry textbook. Drop liquid oxygen between two poles of a really strong horseshoe magnet, and it suspends itself in midair until it boils off.

Now you wanna talk useful applications of L02...

You have to scroll down a bit to get my point, but nothing good comes without effort. Or something.

Nayt

It's being acted on by a force stronger than gravity. If you're very careful with some magnets you can make things float via repulsion (think MagLev trains).
There, that about exhausts everything I actually understood from physics last spring.

Dreadful article. The oxygen isn't 'defying'
gravity at all - it's simply that the Meissner effect is pushing the O2 upwards. Are you 'defying' gravity when you walk up the stairs?

Yes. Gravity wants me to stay on the first floor. Climbing stairs is like slapping it in the face. Sometimes Gravity punishes me by making my lunch fall to the floor.

i am just happy that gravity on earth is not as strong as on some other planets.

Apologies, quantumfluff. Bad day. (My job would be *SO* much easier if it wasn't for the users !)

No problem. People constantly misunderstand my humor when they can't see the expression on my face. I could use a smily to help, but I think that's too much of a give away.

i personally found that extremely funny, quantumfluff. i don't know why, but i laughed out loud when i read that-

i think that we should all take up arms against gravity. we'll show that SOB what we're made of. i'm gonna go climb my staircase a few times.

Thank you. That's the service I hope to provide. All the better if your drink comes spewing out your nose when it happens. When I can get someone to noser in a meeting at work I feel like the king of the world. (you're never to old to be childish)

But wouldn't that also involve climbing *down* your staircase a few times, thereby letting gravity have it's way with you?

Not quite. The Meissner effect is what kept the magnet suspended above the superconductor. The liquid oxygen was formed by condensation on the surface of the liquid nitrogen (I think it was nitrogen, anyway... the site seems to be having trouble so I can't check) and then was pulled upwards by it's attraction to the magnetic force from the magnet, not repelled from the superconductor. In the absence of a superconductor (and thus the Meissner effect), a strong magnet will still attract liquid oxygen quite readily.
