Quarter stick

A quarter stick, colloquially known as the M-1000, is a large firecracker that falls within a certain range of dimensions: 1" x 2.5" or 3/4" x 6".

Like the others, a piece of visco fuse 2 to 4 inches is protruding from the side or end.

The term quarter stick is based on a quarter-stick of dynamite, which it somewhat resembles.

However, quarter stick firecrackers do not contain nitroglycerin as dynamite does, and have far less explosive power.

In the United States, quarter sticks and similar large firecrackers are illegal to manufacture or possess without an ATF High Explosives Manufacturing License.
