Some pretty interesting things can be made with water like making spirals out of it when being poured can be done by using certain sound frequencies to manipulate water.
Pretty simple setup if you want to recreate it at home. All you really need is a powered speaker, a hose attached to a tap, some tape and something that will generate sound at 24Hz through the speakers (tone generating software being suggested, but signal generators will work too or a tuba playing its lowest G would also work if that is more your thing). Most crucially you need a 24 frames per second (fps) camera.
The speaker causes the hose to vibrate, shaking it 24 times a second. To the naked eye this looks like something of a blur, but if your camera is also taking a shot every 24 seconds the video looks like the water is frozen in space, with just slight changes to the position of the drops.
Adjust the frequency up slightly and the water appears to be falling with marvelous slowness – the shaking now occurs every 0.04 seconds instead of 0.0417, so the drops appear to be moving at 4% of their real speed.
Things really get interesting when you make the frequency just slightly lower than the required speed (have your tuba player go to F). Now the water appears to move upwards. This is known as the wagon-wheel effect, after the way wheels in Westerns can seem to rotate the wrong way when they are moving more than half way round between frames.
Brusspup also explains that although you cannot see the in person you can see them at night using a strobe light.
A similar situation has also been found using florescent lights in workshop environments. When bulbs flicker, moving parts of machinery like saws can appear to stand still. VERY DANGEROUS!!
