“And the cursed pumpkin rose up from the earth, carried to the sky by the spirits of All Hallows’ Eve.” Or in other words, Andy put a superconductor in a pumpkin and levitated it on a magnetic track.

Happy Halloween! To celebrate this year we thought we’d have some fun with a pumpkin and superconductor. Inspired by this previous video (http://youtu.be/zPqEEZa2Gis), Andy took to the prep room to imbue a cheerful pumpkin with the eerie powers of superconductor levitation.

Coolness.
Ohmigosh that is so cool
Lmao ummm wateba
Sorcery!
YEAH SCIENCE
That's cool!
Amazing dud
Wow great video!! I love how easily and smoothly it follows the track.
LOVE love love it
Headless horseman disapproved this video
That's just awesome! Great video.
That did not look like an iPhone 5 or later
Imagine you made this with a big pumpkin. lit the outside on fire. Then had it charge at children who approach your house on halloween. Right before it gets to them it cranks a turn and disappears back in to the darkness. They would run so hard and so fast away
Epic! If you put the whole track in a vacuum and gave the pumpkin a push somehow, would it do a lot more loops or lose energy with each turn?
Did you try using the expanding Nitrogen to propel the pumpkin like a really weird rocket?
Hi Ri, Does the superconductor exert a force on the track and if so what would be the size of that force relative to weight.
Harry Potter magic in real life
how would two superconducting magnets interact?
Wow, such a simple and elegant explanation. None of that "quantum" bs.
if you push the pumpkin as hard as you can will it stay on the track?????
whats the liquid nitrogen for though
Would it work in space, since there is no gravity pulling it to the track,
and thus not creating the necessary currents needed for this to happen?
Hmm, another name for a Rock Band—"Levitating Pumpkins"
now a slight improvement comes to mind: a tiny hole at the back through which the gas could exit will provide a small jet to drive the object. nicely done nevertheless
