Water Running Through a 24hz Sine Wave

We already wrote about Brusspup and his crazy anamorphic illusions – and now he’s back with new tricks! This time he attempts to bend water using an audio speaker set to produce a 24hz sine waves. His first video, testing the principle, made it look as the water was going upwards, but now Brusspup has taken it up a notch and actually makes the water flow in shapes and patterns!

Unfortunately, the trick is that you can only see it through a 24 fps camera. The installation consists of a water hose that’s attached to a speaker with 1 or 2 inches hanging down, so that when the speaker produces sound, it vibrates the hose as well. An audio cable is attached from the computer to the speaker and the sound software is adjusted to 24 hz. When Brusspup turns on the music and the water, the result he sees through his camera is water running down in the shape of stairs and spirals. You can get different results if you set the frequency to 23 or 25hz as well!
