GUNGE TANK
The two Housemates nominated this week will take it in turns to stand behind a plinth. They must guess three of the Housemates who nominated them. The housemates they choose will take it in turns to stand in a gunge tank in the Garden. Deana and Lydia will gunge those housemates that they think are guilty of nominating them – Big Brother will then reveal whether or not they guessed correctly. If the gunged Housemate did in fact nominate them, they will win points for the group. However, if they gunged an innocent Housemate, they will lose the points instead.

I like the sound of that one!
