The Rocket is made of a 3 inch PVC pipe capped at both ends. The pipe is filled with 6 pounds of a Potassium Nitrate/Sugar mixture. Potassium Nitrate, also known as saltpeter can be obtained at any gardening center or pharmacy. This wire leads to an igniter planted in the core of the rocket. When I attach the alligator clips to the 6 volt battery, it completes the circuit sending electricity through the wires. A nickel chromium wire is banded at the tip and begins to glow red. This ignites the pyrotechnic material which consists of a high temperature nitrocellulose/black powder pyrogen. Nickel chromium is the same wire used in toaster ovens.
When the propellant burns, the reaction yields a white smoke which expels through the nozzle. This 1/4th inch nozzle concentrates the smoke making the rocket propulsion more powerful causing the propellant to burn faster under a higher pressure. The Newtonian law is then applied: “to every action there is an equal and opposite reaction.” The rocket expels a powerful force outward, thrusting the skateboard the forward
