fedex - 2014-01-02 for HE is the KumkwaatHaagendazs!
Simillion - 2014-01-03 For he is the SkeetsharkCadillac!
godot - 2014-01-02 Excruciating to dogs. A 1 cm wavelength is about 35 kHz.
jreid - 2014-01-02 But what does it *sound* like? Because I'm willing to bet it ain't the Blue Danube floating those foam fluffs.
Old_Zircon - 2014-01-02 Awesome, I heard that this was in the works a couple years ago but I didn't expect it to get this far.
Old_Zircon - 2014-01-02 Actually I'm thinking of something else, I've known about (much cruder) versions of this for a long time but what I heard about a couple years ago and then never again was an early prototype of a system for adding 3d tactile sensations to touchscreens using a similar approach.
Oscar Wildcat - 2014-01-02 Unlike many of these clips, the creators were kind enough to provide a short abstract of previous work. So you can see the idea is an old one. There is a demo of the '75 work at one of the science museums in the New York area; basically a horizontal tube with a loudspeaker to drive the whole into a standing wave resonance. small particles inside the tube rise up in the nodes of the standing wave and levitate as seen here.
BHWW - 2014-01-02 Then there's a horrific accident at the lab and a supervillain is born.
Oscar Wildcat - 2014-01-02 That's pretty brave. At those sound pressures I might expect to see cavitation in a fluid, like your ball sack. In fact, Putterman et al claimed that in a spherical resonator ( like each of your actual nuts ) you can get shock waves in the center that trigger tiny fusion events. You'd have a little fusion reactor in each ball. It might hurt a bit; but SCIENCE!
BorrowedSolution - 2014-01-02 I'm not seeing a downside. In fact, your explanation only entices me more. Would it be possible to recharge my wireless devices that way?
BorrowedSolution - 2014-01-02 Also, what if these 'spherical' resonators are more on the oblate side? Or extremely on the oblate side? And what if one of them is a bit smaller than the other?
poorwill - 2014-01-02 Also his balls are fusion reactors.
