This video demonstrates how to make black powder at home. For this project, you will need the following: a spoon, a scale, potassium nitrate, charcoal, a container, and grinding media (non-sparking), sieve, a bowl, and sulfur. Pour all of your ingredients into the container. It is best, if your container is half filled with grinding media, before you add the chemicals. You should allow it to grind for a couple of days in your mill. The more it grinds the finer it will be. This can be done with a mortar and pestle, but it will be more difficult and time consuming. After your chemicals are done, sift. They are ready to be used. To test it, add a fuse and light it.
