It's an ultra conductor. The physical properties change when the metal nears absolute zero.

All I know is that you can make Ice-Cream out of that stuff he is putting over the thingy...!
We did that once in our class! *mmmh*

gj, i wasn't expecting an answer
nope sorry.
Yes. The black tingy is super cooled and gets a cool (not cold cool) magnetic field around it.
This is based on the Meissner Effect in superconduction... A superconductant material that is cooled below its threshold temperature (ie it becomes superconducting). Basically every magnetic field applied to that material induces an electric current inside the material that displaces all existing magnetic fields.
On a sidenote: a practical application of this effect exists in the so called Maglev-Trains (Magnetic Levitation Train).

I saw this experiment conducted at Argonne National Laboratories outside Chicago. http://www.anl.gov/
Basically, it's experimental purpose is to levitate moving objects in order to reduce the friction, thus greater speeds, acceleration and cost-savings.

Are you referring to the liquid nitrogen? If so I'd be very interested to know how you would turn a relatively stable compound such as N2 (which consists of only nitrogen - duh) into ice cream in a classroom.-Solv3r- wrote:

And you actually ate that liquid nitrogen ice cream? And you're still alive? Yeh whatever...
I did take sulfuric acid and mix it with vinegar and took a sip of it one time...

if you can explain why the holes in this video repell each other, then ill be more impressed
