Olympic Torch

The Olympic Torch was a traditional part of the Olympic Games. In the 2012 Olympics, an athlete bearing the torch was chased by a Weeping Angel into the Doctor's TARDIS. The Eleventh Doctor used his sonic screwdriver to make the torch expand and consume the Weeping Angel. (TV: Good as Gold)

Also during the 2012 Olympics, Rose Tyler used the torch as a power source for an Isolus pod, as it was both a heat source and a "beacon of love". As the torch-bearer was unable to continue upon reaching the stadium, the Tenth Doctor used the torch to light the Olympic Flame. (TV: Fear Her)
