so, i'm one of those ppl who doesn't care as much as the effect of the light but i'm more interested in how it works, and the water effects have always made me think and my brain hurts from thinking soo much, so can anybody explain to me how they work???

From what I can remember. There are two rotating wheels in them. One is ripply glass like your mommas old shower door. Its what gives the wavy effect. Also there is a color wheel that gives it the color. Thats basically it. They do look awesome projected on the walls or dance floor. I bought two of them & wouldn't mind a few more.
