The Big Brother Museum will open its doors today with housemates challenged to make a show of themselves.

It's a shopping task and BB has told the housemates that five of them will be exhibits and must stand still and in silence in order to pass the task. The remaining two will be security guards and it will be their job to inspect the statue-like housemates when a red light on their desk flashes, noting down any movements. They will remain in the outside the museum when not inspecting.

If the security guards fail to do their job to Big Brother's satisfaction, housemates will spend their last week on an economy food budget.

Sounds exciting doesn't it? What do you mean not really.

That's because Big Brother is only telling the security guards half the story. They have been called to the Diary Room, leaving the remaining five to learn the truth of the task.
