Rancorous Carpe's trap

"...baited with an assortment of weapons he believed would be irresistible to Peeves, and a vast enchanted bell jar, reinforced by various Containment Charms, which he intended to drop over the poltergeist once he was in place."

- Description.

This trap was assembled by Rancorous Carpe, then caretaker at Hogwarts School of Witchcraft and Wizardry, in 1876 in an attempt to capture and contain Peeves. It consisted of a variety of weapons, including several cutlasses and crossbows, a blunderbuss, and a small cannon, which were all placed under a large bell jar enchanted with Containment Charms. Though Peeves fell for the trap, it failed to contain him, and Peeves was then free to assault the school's population with the weapons from the trap. This led to a three day standoff between Peeves and the school body, only ended when Headmistress Eupraxia Mole drafted a contract granting Peeves additional privileges.
