This is a reasonably common piece of street magic. A performer appears to float above the ground, balancing only on a stick or a cane that can't possibly be strong enough to carry their weight. It's like they've found a way to cheat gravity.
In reality, there's a reason these performers are always wearing baggy clothes. The clothes hide a platform, and the cane is anchored to the ground using a heavy platform. They're actually sitting very comfortably, and the laws of gravity haven't been broken.
