Casual Friday — Mercury sculptures

OK, a lot of people these days are concerned about too much mercury in the fish they eat. So it’s probably appropriate that when Theo Gray went to make some small, cast metal fish, he made them from mercury.

Hint: it helps to have some liquid nitrogen on hand.

Just remember, kids — the behavior of materials depends on their melting point. Materials that are liquids at room temperature can behave very differently when they’re chilled enough…

Thanks to BoingBoing and for the video!
