BOTTLEROCKET
Bottle rocket
A bottle rocket is a very small skyrocket. A typical bottle rocket consists of a rocket engine attached to a stabilizing stick. The user can place the stick in an empty bottle, and ignite the rocket engine; the mouth of the bottle guides the stick, stabilizing the rocket in its first moments of flight. In India, bottle rockets are set off during the Hindu festival of Diwali, and are sold in the millions.The above text is a snippet from Wikipedia: Bottle rocket
