Playing at NMR

Ever the chemical information innovator, Adam Azman who teaches organic chemistry at Butler University has devised a "coin flip" game to help chemistry students get to grips with the concepts of nuclear magnetic resonance spectroscopy and more specifically the idea of coupling. By assigning a value to the head or tail when flipping two pennies, thousands of coin tosses will add or subtract from a tossed "quarter" - the "set of equivalent protons" giving a statistical 1:2:1 ratio of total values $0.23, $0.25, or $0.27. He points out that using a nickel will allow you to augment that game with J-values. You can play the game here -
