Stuff attached to an Acme detonator, in cartoons (3)

I believe the answer is:

tnt

(Other definitions for tnt that I've seen before include "Initially, powerful explosive" , "Type of high explosive" , "Explosive compound" , "Explosive stuff" , "Very powerful explosive, compressed" .)

I've seen this clue in The New York Times.
