Sonic tractor beam invented (w/ Video) [This is Cool]
Hmm, now What could we do with this?
I envision filling up Air Force One with the worst of our kakistocracy and sending it to the Moon!

On a more serious note, though, you have me wondering what speaker/frequency configuration would be required to construct such a "pea shooter". The sonic tube will likely have to extend into the upper atmosphere and some kind of sonic peristaltic action would be required to provide the "spit". Of course the entire tube wouldn't have to exist at the same time, only the part encapsulating the object being "spat" as it accelerates through the atmosphere. The energy required would be enormous and the materials the speakers would need to be made out of would have to take a considerable stress. I figure the wire gauge would have to be substantial as well and, if constructed at Cape Canaveral, half of Florida would go dim when they fired it up. Interesting to cogitate.
Edit: A further thought is it probably wouldn't work due to the limitation of the speed of sound.
