Unlike a rocket bottle with fins at the base and a bottlecap nosecone&mdashthese bottles have their fins at the top end and it&rsquos the base of the bottle which represents the detonating end.
With the rocket bottles, one imagines them taking off, upwards. The thrust of the bomb bottle, however, is presumably downward. A more fitting metaphor, perhaps, for alcohol&rsquos depressant qualities.
