A round red seamless leather ball, 12 inches in diameter - that is, about the size of a Muggle football - one of the four balls used in playing the game of Quidditch. The Quaffle is the ball with which Chasers score goals, and due to the nature of the game must be caught and thrown one-handed, since the player must at the same time control his or her broomstick (PS10, QA3, QA6).
The design of the modern Quaffle dates back to the first half of the eighteenth century. Originally Quaffles were not enchanted objects, but were ordinary leather balls, sometimes with finger holes or straps (QA6).
The red colour of the Quaffle was first applied in the winter of 1711 to make it easier to see when dropped to the ground. Ironically, soon afterward the modern Quaffle - technically named the Pennifold Quaffle after its inventor - was developed, making the colour change unnecessary: Daisy Pennifold had the idea of bewitching a Quaffle to slow its fall through air to about the speed of falling through water, so that Chasers had a better chance of catching the ball in mid-air rather than continually retrieving it from the ground (QA6).
There are three types of Quidditch balls, each of which is magically enchanted to behave in a particular way. The enchantments are very powerful to prevent tampering.
Broomsticks designed for Quidditch, often refered to as "racing brooms," contain a number of special features and enchantments to make them faster and more agile than a standard flying broomstick. More information can be found on the broomsticks page.
Members of the wizarding community use quill pens and parchment for writing rather than modern Muggle pens and paper. Various birds' feathers may be used to create such quill pens, including magical birds. In addition, specific kinds of quills may have spells placed on them (see further entries under each specific type of quill, below).
Various kinds of feathers have been mentioned as being used for quill pens in the wizarding world.
Auto-Answer Quills are banned from the examination hall during tests at Hogwarts (OP31).
quill, magical (Hogwarts)
A magical quill at Hogwarts detects the birth of each magical child, then writes his or her name down in a large parchment book. Every year Professor McGonagall checks the book, then uses this information to send out owls to these children as they approach their eleventh birthdays (Sch1).
Rita Skeeter carries an acid-green Quick-Quotes Quill in her crocodile skin handbag. When she wants to write, she sucks briefly on the tip of the quill, then sets it up on a sheet of paper (GF18, OP25).
quill, Umbridge's detention
A long, thin black quill with an unusually sharp point, this quill does not use ink. Instead, when used to write, it magically slices into the back of the hand holding it and draws blood in place of ink. The cuts at first heal immediately, but over a long session the damage will be repaired more and more slowly, until the hand is finally left raw and bleeding.
