This time, several contenders become baffled by things as apparently simple as a high five and a fish tank, which doesn't bode well as they continue their quest to win Greg's gilded bonce. Alex Horne records the minutiae of each task as Ardal discovers that a mallet floats, Bridget has a present for the Taskmaster and Sophie covers some keys in saliva.

Task 3: Make the water level rise to the top of the big fish tank. You have 15 minutes to gather six things, then you must put all six things in the big fish tank.

Closest water level to the top of the big fish tank wins. No fish tanks may leave this room. Your time starts now.

- Ardal: Uses a unspecified quantity of water, a brick, a croquet mallet, two satsumas, and a figurine of Archimedes - at the bottom of which was a map of the room, which no-one spotted, locating the position of six bricks with letters on spelling: "Eureka", which would have risen the water level to the perfect height. - 5
- Judi: A hand of bananas, coffee jar, and four bottles. 18mm from the top. - 4
- Chris: Disqualified for making water leave the big fish tank. - 0
- Bridget and Sophie: Disqualified for taking the small fish tank out of the room. - 0
