El Cheapo banger made simply from two milk bottle caps etc,hot glued and duct taped in place,filled with match heads,imporvised fuse added and got a cool little portable banger/fountain thing.

Step 1: Staring Up and Finishing Up.

Hot glued a straw piece to act as a tube for the fuse to enter,done before matches and fuse added for obvious safety reasons.

Step 2: The Video Test.

Less bang more of a fountain with a spread of flame and matches in almost all directions,came with a large whoosh sound,the straw acted as a funnel for the matches to escape so a more sealed bottlecap for a bang probably the way to go.
