Scott and Sara have become security guards for this week's final Big Brother shopping task.
As was revealed earlier, this week the housemates will working in Big Brother's brand new museum.
While Scott and Sara will patrol, the other housemates must become exhibits, and stand still throughout the task. They must not talk or move.
However, the guards are unaware that there's a huge twist.
While Scott and Sara were in the Diary Room getting their outfits, the exhibit Housemates were informed that they do not have to stand in the museum and not talk or move throughout the day.
Instead, Exhibit Housemates will merely have to stand still and not talk for the first hour only and during the guards' inspections.
In actual fact, the exhibits will be sneaking off through a pyramid into a secret chamber which will be packed with wonderful treats for them to enjoy.
Big Brother will simply play the footage of the first hour on a loop to the security guards’ monitor – so the exhibits appear to be there all along.
When the Housemates see the pyramid door open, they must take their outfits off, leave them in the museum and crawl through the pyramid into the secret chamber.
When Housemates see a flashing red light in the secret chamber this means the security guards will shortly be called to do another inspection. Housemates must then crawl back through the pyramid and get back into their costumes and positions in the museum, leaving no trace that they have moved.
However, if Housemates are too slow getting back or rouse the suspicion of the security guards they will fail the shopping task.
Each time the Housemates renter the secret chamber there will be even more treats
