Fuse

Step 4 Mixing the black powder paste

You can do this in either a separate container and pour it in, or just do this in the container with the string. I prefer a separate container because it is easier to stir and get to a smoother consistency, which results in a higher quality fuse.
For each batch I make I use about 90 grams of black powder and 9 grams of dextrin. You can increase or decrease this amount as needed, just remember for every 10 grams of black powder use 1 gram of dextrin.
To make the liquid solution mix 1 tablespoon rubbing alcohol and 3 tablespoons warm water in a separate cup. Mix the contents of the cup and then slowly pour it into the container with the black powder and dexetrin. You will probably not use all of the liquid in the cup, so pour slowly and stop every few seconds to stir the mixture. Once the consistency is similar to white glue stop adding the water/alcohol mix. Before you pour this mixture into the rig, take the string coming out of the front of the container and tie it to one of the supports you choose to "web" the fuse from.
If you havent already put on your latex gloves and dirty clothes. Pour the mixture into the tupperware with the string and go to the next step.
