. A typical bottle rocket consists of a rocket engine attached to a stabilizing stick. The user can place the stick in an empty bottle (hence the name), and ignite the rocket engine; the mouth of the bottle guides the stick, stabilizing the rocket in its first moments of flight.

, and are sold in the millions.

These rockets have been made at least since the early decades of the 20th century, and in many countries, including Japan, China, and Macao. The older type of bottle rocket was typically a black powder skyrocket with a motor about 2 inches (5 cm) long and up to 0.375 inch (9 mm) diameter, mounted on a thin bamboo splint and often having a small report charge.

Modern bottle rockets are small and very cheap. They are often sold by the box for less than $US 0.20 each. In Thailand

    . This will typically use a black powder-type fuel, possibly with additives to produce a decorative spark trail as the rocket ascends, but they have also used other chemical reactions (eg. vinegar and baking soda) for thrust. The fuel is pressed to form a solid grain inside a cardboard Lub tube; this tube is sealed at the top, but open at the bottom. When the fuel is ignited from the bottom, hot gases are expelled downwards, propelling the rocket upwards. Other fuels are possible. A common alternative choice is whistle mix

  • The guide stick. A typical bottle rocket, with no fins or other stabilizers, relies entirely on its stick for stability in flight. The stick's length and weight are chosen to achieve this.
