Bunsen burner

A Bunsen burner was a piece of laboratory equipment used to heat substances.

On a freezing March day, science teacher Ian Chesterton tried to heat up his Coal Hill School lab by putting the Bunsen burners on full blast — to no avail. (PROSE: Time and Relative)

The First Doctor compared trying to explain the mechanics of time travel to Ian to teaching a primate the principles of a Bunsen burner — "the human mind is simply not equipped to deal with four-dimensional physics." (PROSE: The Witch Hunters)

When Captain Mike Yates secretly made hot cocoa in the Third Doctor's lab, he used his Bunsen burner. The heat from the burner activated a Auton troll doll the Doctor had taken from Mary Farrel, and it attacked Jo Grant. However, Yates shot the doll several times with his pistol, destroying it.

The Eleventh Doctor's TARDIS console included a bunsen burner. (COMIC: Bad Vibrations, GAME: TARDIS)
