Big Brother - Season 1 Episode 23

The housemates were given their fourth weekly task on Day 23, which required the eight remaining housemates to learn the Semaphore signalling system. The housemates worked in pairs and attempted to both communicate and transcribe messages using the code. They wagered 35% of their budget on the task, which they failed. The group missed their opportunity to enter the storage room when it opened, thus their food remained locked. The housemates were later given a second task in which they had to perform a good deed; the housemates passed this task, thus earned the food.
