Bernoulli Halloween decoration

I'm sure most of you have seen science exhibits where the Bernoulli principle is used to make a ball levitate in mid-air. Has anyone tried making a Halloween decoration based on the idea? It'd be pretty cool to attach some streamers to a white ball, paint on some eyes, and have a levitating ghost.

If you had the air nozzle moving or adjust its air flow, you could have the ghost also move around.
