New link?

The video doesn't work anymore. New link anyone?

That is pretty cool. I did a demonstration in high school physics class that used just water suspended above a sub-woofer enclosure to show the effects of reversing polarity on one of the woofers. It earned me an a, as the waves completely disappeared from the water when the polarity was reversed, which demonstrated the physics behind noise cancellation. I thought I was pretty cool having thought of that but if only I had used cornstarch water instead!!!

#1 is right, cool and creepy at the same time, I think it’s worth investigating some more :)

Earlier this year I bought 4 tactile transducers (Aura AST-1B-4 bass shakers) of which I stuck 2 to the back of the chair I’m sitting on so I get a nice additional bass rumble when watching films, but still have 2 spare… I think a trip the shops for some cornflour is in order

Thanks for sharing. Ever since science classes in elementary school, I’ve loved the effect of cornstarch and water together. Neat to see someone use it for something so odd-looking.

This is really cool. My family tried it after seeing this video but we couldn’t really get it to work as well as shown. I don’t know if we didn’t have enough rumble, but the most we could get was small ripples.

Neat. The rice resonance video is another really cool one:

A ferrofluid is a sort of liquid with (usually) micro or nano particles of ferrimagnetic material, such as magnetite – but it’s still a newtonian liquid. I have experimented with ferrofluid before (making a “liquid clock”) and I gotta say I believe it’d be pretty boring to use one with a subwoofer. To make the particles cluster together, a kinda big magnetic field has to be applied. I believe the woofer field wouldn’t be enough to really “shake” things. Still, ferromagnetic has a LOT of potential to be discovered, and is a lot of fun to play with.

Wow, that’s insane, if someone could figure out how to build a self contained, self sustaining version of this, I’d definitely build one for my sound system.

sweet man, i can see some crazy badass music video’s coming from that… you best produce and cash in or else someone else will…

that just looks soooooo creepy and wrong. at the same time it looks sooooooo cooool.
i love it.
it’s weird off the wall surprises like this that keep me hitting this site every hour or so throughout the day.
