Harry Blake, Faye Palmer, Alex Rose, Aaron Allard-Morgan, Louise Cliffe, Jay McKray and Tom O'Connell were told they could win a '90s rave if they succeeded in the food-eating task.
Big Brother gave the housemates shot glasses filled with ground cinnamon and when they heard a klaxon sound, they had to swallow the food without drinking any liquids or letting any escape their mouths.
To pass the task, they needed three out of the seven housemates to complete the challenge.
Aaron, Jay and Harry managed to swallow their shots, winning a rave for the house last night (Wednesday).
Aaron, Jay, Harry and Faye face eviction this Friday following Jem Palmer's decision to walk out of the show yesterday.
