Serpent Birthday Card

A serpent is symbolic of birth and rebirth. 

This green card shows the structure of a chemical called mercury thiocyanate. When heated, this chemical undergoes the "Pharaoh's Serpent" reaction creating a large coiled solid mass resembling a serpent. Sounds crazy, but it's true!
