I tried this with some of my German handmades last spring in sunlight. The water really brings out the colors and especially mica flakes. It was a nice experiment and the pics turned out great.
OK, I will do it myself then
I think this one is pretty ugly (which makes it special somehow). Quite big, no core, just some small outer bands (but four colors) and a big uncontrolled air bubble.
