"The levitating force is strongest when the object is about the same size as the wavelength of the ultrasound waves." A wavelength of 5 to 6 feet would be an extremely low frequency and I'm sure not too comfortable to our bodies or ears. I guess we won't see ourselves levitated in the near future...

I've put the original Nature News article in instead. The problem with Nature News is that it's only free for a week, so the original link will die. Furl saves webpages for you, but I didn't realize you had to log in to see the ones I've saved. There has to be a better solution to this problem!
