Blasting Curse

The Blasting Curse causes anything that the spell comes into contact with to explode. A possible lesser version of it might be the Blasting Charm. The incantation is Confringo.

Known Uses

 * On November 1, 1981, Peter Pettigrew used an extremely powerful Blasting Curse to destroy a street and kill twelve Muggles at once while evading Sirius Black, who was blamed for the crimes and Pettigrew's alleged death. The explosion was so fierce, it left a massive crater in the street, with the pipes showing. The Ministry gave an excuse of a "gas leak" to the surviving Muggles, and thought that Black was the one who used the curse.
 * Harry Potter used this curse to destroy Sirius Black's flying motorcycle's side-car during the Battle over Little Whinging.
 * Later that year, Hermione Granger used it in an attempt to kill Nagini and facilitate her and Harry's escape from Bathilda Bagshot's house in Godric's Hollow, but broke Harry's wand in the process.
 * In 1998, during the Battle of Hogwarts, Hermione used it again, nonverbally, to blast Fenrir Greyback away from Lavender Brown.
 * It was possibly used by Augustus Rookwood in 1998 during the Battle of Hogwarts. The spell caused the ceiling to collapse, which killed Fred Weasley.
