Water Illusions can happen when you film fast movement with the right type of camera.

To the naked eye this looks like something of a blur.

But with a fast enough shutter speed a camera can make objects appear like they are frozen in time.

These illusions happen when an image moves too fast for a camera to detect.

This is known as Temporal Aliasing / the Wagon Wheel effect.

Materials needed:

Speaker
Tone Generator (to create vibration for your speaker)
Running Water
Flexible Hose (Pocket Hose purchased for $20 at local store)
Camera that can record at 24 frames a second

How this works...

A 24 hz bass tone is sent through a speaker making the water vibrate 24 times a second.  In a circular motion.

With a fast enough shutter, the camera captures the same image frame after frame.

Creating the illusion of water that is frozen in time.
