That thing looks like a Darwin Award machine.

The water is waving around back and forth 24 times per second along with the 24 Hz sound wave, so to the human eye it would just look like it's diffusing randomly. By recording the water 24 times per second, though, you really only see the water in the same position during each of its "waves", so to the camera it looks like it's holding still in mid-air.

Leave it to Twitter and that stupid "I ****ing love science" Facebook group to strip science down to "OMG THIS LOOKS KEWL <3 IM SUCH A NERD LOL".

I read this and totally understood it. Then I re read it, and got confused.

Then I read it a third time, and now my brain hurts, and I'm scared of you.

How about this: you wave your hand at someone so that your hand went back and forth once every three seconds. Someone is taking pictures of you every three seconds. If you looked at those pictures back-to-back, it would just look like you're holding your hand in the same place each time.

The same thing applies to the water here, except that instead of waving once every three seconds, it's doing it 24 times every 1 second. The camera is the person "taking pictures", except that it's also doing it 24 times per second (since that's the speed it records at).

Does that make sense?
