What a fantastic mind trip. This tree appears to be magically hovering over its tree trunk. What kind of sorcery allows this? Art. Daniel Siering and Mario Shu wrapped a tree in a plastic sheet and then painted the sheet to look like the tree's background. The visual effect makes the background look perfectly seamless.
Cornell researchers are working on a way to make hovering vehicles a reality. By pairing superconductors with permanent magnets, they've figured out a way to get objects to hover with complete stability without any power necessary.
It's a fake. Still neat, though.
