Bucket

A bucket was a container used mainly to carry liquids.

In the 1970s, the Fourth Doctor threw a bucket of metal virus at K1. (TV: Robot)

In the summer of 2007, while facing a Hoix with the Tenth Doctor, Rose Tyler threw a blue bucket of liquid at the Hoix. This was the wrong bucket, Rose had thought the Doctor said blue, but as the Doctor noted, he had said "not blue". This enraged the Hoix who chased Rose and the Doctor until Rose found the correct bucket. (TV: Love & Monsters)
