ABSTRACT
The air is warm and still as nine students set off for bioassay lessons. Their instructor is Dr. Garland Tarleton, a kindly, middle-aged, portly fellow with an Albert Einstein coiffure and a lively sense of humor. After he divides his nine students into groups of three, Dr. Tarleton gives each group the choice of a .44 magnum water pistol and a bucket of water or a precision paintball gun with a supply of red paintballs. Dr. Tarleton warns the groups to choose their weapon carefully because he cannot allow them to change midexperiment. Group 1 selects the paintball gun; groups 2 and 3 each choose a water pistol.
