I recall reading about prisoners who were scheduled for execution by their countries and the ways they cheated the society that condemned them by committing suicide.

One of the individuals who knew what kind of plastic playing cards were coated with, stripped playing cards of the plastic and crammed the plastic into a pipe he scavenged from his bed. After filling the pipe (I have no clue as to how many decks he had to strip.), he beat both ends of the pipe shut and held the pipe over a flame source, which I believe was a single small cooktop in his cell (Must have been somewhere in Europe) until the pipe exploded and killed him.

There are powerful components in everyday items if you know what to look for.
