- Ginny Weasley: "You can't come down here! No, sorry, you're going to have to go round by the swivelling staircase, someone's let off Garrotting Gas just along here -"
- Surly Hogwarts student: "I can't see no gas."
- Ginny Weasley: "That's because it's colourless! But if you want to walk through it, carry on, then we'll have your body as proof for the next idiot who doesn't believe us."
- — Ginny Weasley claiming to dissent passer-bys about the gas[src]
A colourless gas, Garrotting Gas was produced as a result of the creation of a certain potion. Anyone exposed to the gas would find themselves choking and as a result, may suffocate, as the gas caught people by the neck if they passed through it.
In the 1987–1988 school year at Hogwarts School of Witchcraft and Wizardry, Severus Snape gave a flask of Garroting Gas to Jacob's sibling to be used as a defensive weapon against Patricia Rakepick.
Fred and George Weasley were planning to release some in Hogwarts in 1996, during Dolores Umbridge's tyrannical tenure as Headmistress, but they left the school before they had a chance. Their sister, Ginny, merely had to mention it to prevent students from traversing down a school corridor, which allowed Harry Potter and Hermione Granger to break into Umbridge's office to use her fireplace for communication.
A garrotte is a wiry weapon that can be used to strangle a victim, and also may refer to the action of "ripping through" something.
