For this project I used items from around the house to create a pyrotechnic time-delay. Here’s how to make a simple form of a slow burning fuse, because when experimenting with homemade pyrotechnics, you don’t want to be too close if your composition explodes.

Project History & More Info:
Similar to the recipes I tried for rocket fuel and smoke flares in previous videos, I’m using a 60/40 mix of KNO3 and white table sugar by weight. This time I’m making a 60 gram batch, adding it to boiling water, and stirring it in until it all dissolves.
Fuses were homemade by soaking 12 feet of 100% cotton yarn in the solution as the rest of the water evaporated out, then placed on a cookie sheet and baked in an oven at 300ºF for 20 minutes.
These types of devices may not be legal to make or use in your area, so check local laws before attempting to duplicate this project, and as always, be safe and aware of your environment before igniting anything flammable!
