Black snake fireworks

How can I make black snake fireworks from items around my house ... 

An outdoor location where you can light the black snake firework safely without damaging anything... 

Use the sand to form a pile (in your chosen safe outdoor location), and then create a depression in the middle of the sand. This depression is where you will ignite the black snake firework. 

Materials and labour enter into the left(debit) side and come out of the right(credit) side as finished goods. Practically energies like power or heat and the loss of tools, furniture, fixtures and structures should be added to the left side, but these are quite small in firework manufacture-The operations which move the left side elements to the right are almost all physical and are seldom chemical. For example, the manufacture of potassium picrate as the material for whistles or the nitration of pitch for black snakes belong to the chemical operation.
