Dynamite

Dynamite was an explosive material commonly used in mining.

George Wallace kept dynamite in a shed. It was used in the building of a cave on a hillside. The Doctor and John Hopkinson collected some sticks of this dynamite and Baker put them in Richard Harries' pockets. John Hopkinson ignited them with a lamp causing Harries to explode.

The Eleventh Doctor, Amy Pond and Rory Williams killed a Skaratid by having it consume live sticks of dynamite. (DWAM: Mine, All Mine!)
