Yesterday, the Big Brother housemates learned that they had passed this week’s shopping task and would therefore receive a luxury shopping budget of £840…

More on that in a moment, but first, my question is this; as BB took away all the food etc., that they bought with the luxury budget from last week’s shopping for this week’s task, isn’t that somewhat negating the whole point of the task anyway??

Now granted, the housemates may well have had their food and booze etc., brought back in now this week’s task is over, but for two days, they had to do without everything they worked hard in the last task to win!

And again, I know two days worth of eating only what Big Brother provided wasn’t the end of the world, but if I were a housemate, I would’ve put that argument forward to the big guy and questioned the efficacy of even bothering with the tasks if the rewards can be taken away willy and/or nilly. Would that have riled you?

Anyway, back to the Lab Rats task, and the final hurdle for them to cross in order to win saw the ratty housemates given the chance to turn the tables on the all powerful scientists, Lydia, Benedict and Luke A…

The rats were told that they must pretend they’d been fitted with the infamous shock pads – but on their heads, not their bums this time – and therefore leap around in agony when they got a shock which was delivered by the scientists should they get a general knowledge question right.

Adam, Arron and Lauren were the chosen rats for the ‘Cruelty Experiment’, and while they of course knew they weren’t hooked up to the mains, the scientists didn’t know they weren’t.

The object of the exercise was to see if the scientists were humane or just plain old cruel, and this would be determined by how frequently, and at how many volts, they chose to shock the rats.

However, when Lydia, Benedict and Luke A finally agreed they’d put the rats through enough pain, they passed the task by proving that scientists can show compassion.
