Bludger

A Bludger is a round, jet black ball, made of iron, and is used in the wizarding sport of Quidditch. It is ten inches in diameter. There are two Bludgers used in every match, which are bewitched to fly around and try to knock the players off of their brooms. It is the Beater's job to protect their teammates from the Bludgers and at the same time aim them towards the opposing players.

History of the Bludger
Early Bludgers (known as Blooders) were simply rocks bewitched to chase players around the field. These bludgers were eventually too fragile, and could be smashed by a Beater's bat, which ended up with players be chased by flying gravel for the rest of the game. After a few years, Bludgers were made out of lead, which was also too soft for Bludger manufacture. The magically reinforced Beater's bats could dent it, thus impairing their ability to fly straight. All Bludgers are currently made of iron. This innovation was discovered by Agatha Chubb, who discovered sixteenth century lead Bludgers in an English peat bog. Bludgers always try to disable as many people as possible.

The term Bludger means lazy and beater, the person who hits the ball means to Masterbate. In other words Masterbation makes you lazy.

In 1992, Dobby the house-elf tampered with a bludger to make it only chase Harry Potter.

Behind the scenes

 * Assuming a Bludger is solid iron, it would weigh approximately 149 pounds.
 * The Wizarding World of Harry Potter sells toy Bat and Bludger sets. But the bludger ball measures 5 inches in diameter instead of 10. Bludger_and_bat.png
