DIY Slow-Burning Fuse

While making this year’s fun 4th of July fireworks, launching model rockets, or prepping hard for uncertain times, creating a slow-burning fuse out of easily sourced materials is important to know how to do. It’s cheap, fun and affordable. A slow-burning fuse will allow you the ability to be far away from your fireworks, ensuring maximum safety for you and your onlookers.
Here’s how to do it in a quick, cost-effective way.

Materials:

Potassium Nitrate(KNO3)
Powdered White Sugar
100 percent cotton yarn
Digital Scale
Frying Pan
Cookie Tray
Small Tupperware container
Medium-sized Tupperware container with a lid
1/3 Cup of water
Oven
1 wooden spatula

Instructions:

Cut 12-feet of yarn and set it aside.

Using your digital scale and a small Tupperware container, measure out 24 grams of white powdered sugar.

Next, measure 36 grams of KNO3.

Mix the two powders together in another Tupperware container and shake the 60-gram mix vigorously.

Place your frying pan onto the stove burner and heat it on medium. Make sure it is hot enough so that water will boil immediately when poured into it.

Pour 1/3 cup of water into the pan.

Carefully pour the 60-gram mix into the boiling water.

Stir until all of the powder dissolves. Then let the water evaporate. You should have a frothy white bubbly mess in the middle of your frying pan.

Now, drop the 12-feet of yarn into the frying pan. Hold it by the end as you feed it into the pan, so as to prevent it getting too entangled or knotted. Using your wooden spoon, move the yarn around so that it is completely saturated by the mixture.

Carefully, so as not to burn your fingers, pull the yarn out of the frying pan and place it on the cookie tray in a pattern that resembles waves.

Preheat oven to 300 degrees.
Place tray in oven for 20 minutes until the yarn takes on a goldish, brown color.

Remove tray and cut the yarn into smaller pieces that can then be used.
