Ron Weasley's Taped Wand
Brilliant Hogwarts Hospital Wing
During his second year at Hogwarts, Ron Weasley broke his wand in an accident involving his father's flying car and the school's Whomping Willow. Despite his attempt to repair it with Spello-tape, its magical capabilities were damaged beyond repair. Spells cast using the wand frequently backfired, a feature that actually ended up sparing Ron's memories.
