This Video Will Blow Your Mind

The similarity between sound pressure waves and audio waves is not coincidence.  Both air and water are closely related by physical laws, even though one can’t be detected by the human eye.  The way a sound travels is no longer a mystery to the scientific world, but it once was.  It could be heard by the human ear, but the science of how it reflected and reverberated was not mathematically understood yet.  The best attempt to understand characteristics of sound was by running it through water.  Ancient civilizations made use of the sound effect on water to create some interesting devices.  An old Chinese rubbing vessel would create a frequency by running wet hands over the edges of the device, and the sound produced by it would cause the water to erupt in the air!

Today, we understand exactly what types of modulating noise will have an effect on liquids like water.  Sin waves even have their own shape that is unique from all others.  The pattern repeats itself in the liquid giving the water an effect of floating in the air by itself.  This actually works out to be a cool science experiment and doesn’t require any more than running water and a noise generator.
