Dunk task flops face 'Big Brother' eviction

Six 'Big Brother' contestants will face the public vote tonight after losing a biscuit dunking task to become fully fledged housemates.

The non-housemates each tried to dunk a biscuit in a mug of tea for the longest time, with 18-year-old Cairon Austin-Hill winning with a digestive that lasted 25.5 seconds.
