What do you get when you combine parts from an old battery pack with some common household ingredients? Mix them together and you get these .. A batch of super cheap, and easy to make, smoke flares.

Project History & More Info:
This recipe is similar to ones tried in amateur sugar rocketry. I’m using a 60/40 mix of KNO3 and white table sugar by weight, and I’m going to make a 400 gram batch to fill 10-15 containers that I’ll use for smoke/signal flares. My testing indicates that the finer the composition is mixed, the faster it burns. I want these to burn slower so they don’t take off like rockets, and produce more smoke, so I’m trying not to mix them more than I have to.
I got the containers for the signal flares by hacking open an old cordless drill battery casing, and taking the paper casings from the individual battery cells.
Fuses were homemade, and made in another project.
