Ice #chess set Molds

I thought it would be interesting to make Ice cubes in the shape of chess pieces, use food dye (or Kool-Aid) for coloring the black pieces(you could then play a variant of timed chess, where a piece is gone once it has melted beyond recognition). Warning: not recommended for cardboard chess boards.
I also thought about Chocolate chess, though I suspect eating the pieces you take would be required.
You could use this with just about any liquid that solidifies, such as latex, but I'm not sure why you would.
