Water + Subwoofer = One incredible optical illusion [Video]

Water + Subwoofer = One incredible optical illusion [Video]

Gravity is a force that is unconquerable to man, at least for men (and women) that don’t rig up their subwoofers and video cameras for this incredible trick.

As the video below shows, a subwoofer producing a 24Hz sine can be used to create a very cool optical illusion, with the water caught ‘frozen’ or running backwards simply by varying the frame rate on the camera.

F**k it, we'll do it live!

Our biggest ever edition of TNW Conference is fast approaching! Join 10,000 tech leaders this May in Amsterdam.

YouTube user ‘Brusspup’, who shot and published the video, explains more:

Basically your cameras frame rate is synced up with the rate of the vibrations of the water so it appears to be frozen or still. Now if you play a 23 hz sine wave your frame rate will be off just a little compared to the sine wave causing the water to “move backward” or so as it appears. You can play a 25 hz sine wave and cause the water to move slowly foward.

Awesome!
