Coloured water and tinfoil

I've seen a few abstract shots recently and all I know is that it involved some water, food colouring and tinfoil. What I don't understand is whether it's poured onto the tinfoil and then you try to blend the different colours, or do you fill up some glasses with the coloured water and shine light through onto the tinfoil and photograph the reflection? If someone could help me out that'd be great.

An example can be seen at: (it's the blue one at the bottom right)

anyone?

Interesting idea. You'll likely get better response by posting a picture or two here and not just a link.

Except that you shouldn't post other people's pictures. Just links.

Far right one, right?

And it's a cool pic, but I have no idea how it was done.
