Weight is very important in terms of the performance of your rocket, so make the dowel as light as possible by hollowing out the interior of the nose cone with a drill or knife. Drill a hole from the bottom of the cone, up toward the nose, but do not drill all the way through the nose. 2. Cut a sheet of paper approximately 3 inches wide by 6 inches long.
Carefully drill a 1/16-inch hole through the middle of the stopper. 2.

When the match head is heated to ignition temperature, it forms a hot, rapidly expanding gas within the aluminumwrapped match head (the rocket's combustion chamber). The rocket has two ports, or openings, that vent the gas in a controlled direction. The exiting gas propels the rocket forward. Newton's third law explains why: Any action has an equal and opposite reaction. In this case, if the gas is exerting a force in the backward direction (because that's the way our jet exhaust ports point), the equal and opposite reaction will cause the rocket to move forward.
