He pours Liquid Nitrogen (~-190C°), which makes the square metal, a superconductor. A superconductor does weird stuff, amognst them, holding an external magnetic field in place, and not letting change. If the magnet moves, the magentic field will change, ergo, the magnet does not move
If a magnet is cooled enough it will reverse its polarity. Scientists say same thing will happen to earth in an ice age.
But dude the video is so cool.
what did you end up doing? and what grade did you get?
that is really cool
superduperconductor.
cool
COOL!!!! what did you use?
I think you need a magnet, liquid nitrogen and a coin-sized battery… good luck
can this be a science fair project…i need help
Yep, totally agree
witiich!!!!!
burn that sun of a !@#$
BURN THE WITCH!
sweeet
good
that was awesome
burn him
WITCH!
This is the Meissner effect.
The last three comments are not mine, guys. I think its one of my friends as a prank. I don’t post comments on people’s videos…
-the REAL physiciiiiiiist-
previous 3 comments are not the real me, guys. I think its one of my friends as a prank. I dont post comments on people’s videos…

haha… no, i was jk^^
no, i’m not good at chemistry

Magnet, stupid.
I think its He… Just cooled down like -270C°
wat stops the magnet from being repelled away and slipping off the magnetice feild
so what is the black thing?
some kinda rock or something?
