Gareth Thomas and Nicola McLean nominated themselves as leaders of the challenge, and after being called to the Diary Room, were sent by Big Brother to a special task room.
As various foods and drinks roll along a conveyor belt, Thomas and McLean must describe the items without using banned words.
Remaining housemates Denise Welch, the Shannon twins, Romeo Dunn, Michael Madsen and Frankie Cocozza have to correctly guess the specific food or drink to win it as part of their dinner.
However, if they fail to accurately identify it, it will go into a blender and sprayed in their faces.
The Shannon twins expressed particular opposition to the task, unhappy with the chance of "$2,000 worth of hair extensions" being ruined, and threatening to pull out.
