Israeli Physicist Demonstrates Levitation
Surely if flying saucers existed, they would float around like the disc in this video. The demonstration by physicist Boaz Almog from Tel Aviv University, Israel, at the Association of Science-Technology Centers (ASTC) Annual Conference in Baltimore, Maryland, earlier this week illustrates how a superconducting plate can be fixed in 3D space while levitating above a track of permanent magnets. But this isn't simply magnetic repulsion: the disc can also stay suspended upside down when the magnets are flipped over.
