It's good to see that the art of science is not dead.

When I was young(er) a passing fad was the beer brick. This was a block of clay moulded into a cube with a hole in it the size of the bottom third of a beer can. There were fired in a kiln and then painted. The end result was a block which, when frozen, gave a heat sink which kept an open can ice cold.

They disappeared into time with the trilobites and the sabre-toothed gerbil, never again to be seen.
