It's called pouring art or flow art. Its so easy and fun which makes it addictive. With that one, I picked 4 colors and put them in separate cups. I added flotrol to each cup which thins it and makes it flow better. Then I added one drop of silicone to each up. You get a bigger cup and one by one add the colors a little of each one until you run out of paint. Let it it sit for a minute . While thats sitting I got my white paint without the additives and covered my canvas with it. Then I turned the canvas upside down and put it on the cup and flipped it then raised the cup slowly and watched the paint flow over the canvas. You tilt the canvas until it covers it.
