Housemates who enter the White Room will have the chance to win a money-can't-buy prize of a place in the final.
Conor McIntyre, Sara McLean and Scott Mason will select three housemates to enter the White Room as they are the trio with the least nominations during the series. The house will then be divided, with the remaining housemates not in the White Room competing to win various challenges to earn a luxury shopping budget.
The White Room housemates and normal housemates' first competition is called Space Race. It's a physical game and features one housemate, wearing elasticated bungees, filling a tube with as much milk as possible.
The second competition will feature the divided housemates battling in a Hammer Slammer challenge.
The Hammer Slammer task will involve a housemate having one minute to bash 10 plastic cups out of a total of 30, without hitting one that has blue paint inside. The housemate will know which ones have paint inside because of a plasma screen revealing the details. However, the screen will disappear after 30 seconds, meaning that the challenge is a memory game.
Further tasks will be revealed tomorrow.
The Big Brother White Room episode airs on Wednesday, August 1 at 9pm on Channel 5.
