My gunpowder does not work? Answered
I wanted to craft small salute shells with my DIY gunpowder. I used 7,5 spoons KNO3, 1,5 spoons sulfur and 1 spoon charcoal. Then I put the whole mixture into my Lego ballmill with marbles. After 10 - 12 hours I took the mixture out and ignited 1 gramm. It just sparkled, I had to light it more times because it didnt fully burn. Anyone know what I did wrong? The engine of the lego ballmill is really strong and it is turning fast.
Sorry for my bad english
Thank you very much
