Watermelon: Each wedge is comprised of a handful of seeds, here you can see that there are different layers of translucent and red. It's like some sort of scientific report these pictures. This is just reverse engineering a clay science.
1) the meat of the watermelon.
2) the slightly diluted meat mix.
3) translucent with just a touch of the meat mix.
4) the seed. Make yours black or white.
Just another bullseye.
