This week the Big Brother house has had a scientific makeover as Big Brother attempts a pioneering study to investigate whether the housemates think alike.
Housemates need to prove that they can all think alike in order to win a luxury shopping budget.
Over the next two days Big Brother will call three housemates at a time to The Mind Lab where they will be isolated in three separate booths. Each housemate will get asked a Yes or No question. If all the housemates say Yes to the question they will win 10 points and if they all answer No then they will win 5 points. If all of the housemates do not answer the same then they will not win any points.
What housemates do not yet realize is that the questions they will be asked will be in the form of a dare, this is why they will get more points if they say Yes. If all three housemates say Yes then they must follow through and complete the dare. But in a twist, if one housemate says Yes, even if the other two housemates say No, they will still have to complete the dare.
Located in the living room is a locked Brain Box that contains the amount of points housemates need to pass the shopping task.
At the end of the two days the box will be opened, and if the housemates have achieved or exceeded the points on the card then they will have passed this weeks shopping task and won a luxury budget.
Big Brother continues tonight on Channel 5 at 10pm.
