The perfect visual representation of carbon-carbon bonds! The top fence (alkane) shows a single rail—just like those boring single bonds between carbon atoms. The middle fence (alkene) has two rails, representing the double bond that makes organic chemistry slightly more interesting. And the bottom fence (alkyne) flaunts three rails, just like the triple bond that makes chemists go "ooooh." Chemistry professors probably have this printed and framed in their offices right next to their periodic table shower curtains.
