Harry Potter: 10 Magical Potions With CRAZY Effects
9. Babbling Beverage
Effect: Causes the drinker to start talking nonsense.
Seen In: Harry Potter and the Order of the Phoenix (novel/video game), Harry Potter: Hogwarts Mystery.
A politician's drink of choice, the Babbling Beverage results in the consumer speaking complete and utter gobbledegook for an unspecified period of time.
This particular potion was actually mentioned in the books a few times (in The Order of the Phoenix, the Patil twins brewed up a batch and used it on Professor Umbridge's loudspeakers, in an attempt to undermine her authority), but the movies never showed its effects on camera, though we imagine it would result in something like the Steve Carell gibberish meltdown scene from Bruce Almighty.
Like the Hair-Raising Potion, the Babbling Beverage seems entirely useless, but at the same time, it's so wild and weird that it easily earns its spot on this list.
There's also a curse called the Babbling Curse that produces a similar effect, so witches and wizards the world over are very well-equipped when it comes to getting their enemies to jabber like primitive cavemen/drunk football hooligans.
