Floating Light Bulb.

This isn't a photoshop trick. The fact is that the light bulb is levitating yet it is a powered light bulb. Wireless energy transfer or wireless power transmission is been used in this process.

It will float stably in midair and remain on for years without any physical contact, charging, or batteries. Ironically, with the levitation and wireless power circuitry both on, this entire package still consumes less than half the power of an incandescent bulb.
The bulb and the casing contain hidden circuitry [shown in figures] that uses electromagnetic feedback to levitate the bulb roughly 2.5" from the nearest object, and uses coupled resonant wireless power transfer to power from the housing into the bulb itself.
Here is a link for the movie.
