The housemates must ignore the obvious, but with a slight twist.
The seven remaining celebrity contestants must freeze whenever they hear the bell toll, no matter what is happening around them.
Big Brother is setting housemates a two day task on which amazing rewards and terrible punishments rest.
A giant grandfather clock has been in the living area which will sporadically ring. When the clock rings housemates must freeze completely and become human statues.
Big Brother will be sending a number of surprises into the house whilst the celebrities are frozen, which they must ignore in order to win the task.
Housemates are only allowed to move again when they hear the second clock toll.
The task (in various forms) has appeared on previous series as far back as those that aired on Channel 4, with Big Brother narrator Marcus Bentley and even then-host Davina McCall entering the house.
With the task lasting until tomorrow we wonder if this is how Emma Willis will surprise the housemates with news of the secret eviction.
Celebrity Big Brother 2014 airs nightly on Channel 5.
