Update on the magnetic levitation experiment

So we tried to levitate a magnet in class the other day but... we failed. Most articles on the internet say that the experiment requires liquid nitrogen and since we only had access to dry ice, the experiment didn't work. Not only was it not cold enough, but it was not in liquid form so we had no way to pour it over the superconductor like it shows in the video. Currently we are working on making a train move along tracks using strip magnets. We are doing that tomorrow in class, so we'll let you know how it goes!
