Andrew Goodin, a chemistry teacher at Soldan International Studies HS in St. Louis, MO, whipped up this chemistry themed chess board on the fly:

It is a picture of our chemistry themed chess board. We designed it after school today when we realized that many students in our technology club knew how to play chess, but no board was available and game websites were blocked.

They used flasks for pawns, rooks are the tops of pipettes, knights are crucibles, queens are beakers, bishops are 10ml volumetric flasks, and kings are graduated cylinders. Love it!
