Halloween decoration using bernoulli principle?
I'm sure most of you have seen science exhibits where the Bernoulli principle is used to make a ball levitate in mid-air.
I wonder if anybody has ever 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.
A levitating disco ball could also be neat. Another idea is using a "remote control" kind of device, and having a computer/chip automatically determine how the air nozzle should be adjusted to produce the desired effect.
