Introduction: Solid Rocket Fuel
This Instructable will teach you how to make solid rocket fuel at home with only sugar and stump remover. The solid rocket fuel may be used on smaller model rockets for propulsion. It is very easy to make your own batch of fuel.
Warning! Build this at your own risk
Step 1: Materials
For this project you will need:
Potassium nitrate (I used 100% potassium nitrate stump remover)
Pan (do not use for cooking after this project)
Lighter or torch
Container for fuel, I used a PVC end cap
Step 2: Creating the Fuel
The fuel is a mixture of 65:35 potassium nitrate to sugar
The batch displayed in the images is 65 grams of potassium nitrate and 35 grams of sugar. The potassium nitrate was measured out to its correct mass. The sugar was then added to make the mixture have a mass of 100 grams.
Heat up the pan at a medium temperature setting for 1.5 minutes.
Then slowly pour the powder mixture into the heated pan. Make sure it is spread out evenly.
The mixture should be heated until the sugar begins to turn a brown color. This happened after approximately 2.5 minutes.
Then stir the mixture until white powder is no longer visible.
Pour the liquid into your fuel container. I used a PVC end cap.
After all of the fuel is in its container, place the container in a freezer.
Let the container sit in the freezer until the fuel inside completely cools and solidifies.
Step 3: Lighting the Fuel
Once the fuel is heated, it will burn. Be careful where it is stored.
When you want to ignite the fuel, simply light it with a lighter or a torch.
It should quickly begin to burn and let out large amounts of smoke.
