For this week’s shopping task, the Big Brother 2012 housemates have become lab rats for Big Brother.
As the most intelligent housemates, Benedict, Luke A and Lydia have become scientists.
The others must complete various experiments, whilst the scientists analyse the results.
The first task will see the lab rats have to exercise on a giant wheel in order to win food, after Big Brother emptied the cupboards of everything this morning.
The lab rats don’t know it, but when a female housemate is running on the wheel the group will get treated to nice food, but male housemates will get disgusting gruel.
Will the rats notice the connection?
