At Bit & Nieuw we launched 2012 mini-rockets from an old oil drum. Following the instructions on the label, we did exactly what was told: place it in a container [X], use a certified lighter [X] and keep your distance [X]. Result: a massacre and guaranteed much less safe than regular fireworks (so more awesome).
Step 1: take 2012 rockets
Step 2: place them in a container
Step 3: light it up and start yelling
