- 60 mL Water (Heated on medium heat)
- 36 grams KNO3 (potassium nitrate) which I obtained in the form of stump remover
- 24 grams white sugar
- 1-20 drops of food coloring (color to suit your preference)
(White/gray smoke is the only color emitted, even if you use different colored dyes. Colored smoke cannot be made with KNO3.)
Make the Mixture
Shake the sugar and KNO3 together to get an intimate mixture, then pour into the water and stir until dissolved.
Soak Yarn in the Mixture
Soak about 12 feet of 100% cotton yarn in the solution, then space evenly on a cookie tray.
Bake at 300 Degrees F
Bake in an oven at 150ºC (300ºF) for about 20 minutes, making sure to lift the yarn at 10 minutes to make sure it doesn’t stick to the pan.
Let cool for 5-10 minutes.
Cut to Desired Length
When your sparkle cords are cooled down, you can easily cut them to any desired size with a pair of scissors, and place in clothespin.
