This is a quick video tutorial on how to make those beautiful starmines or black powder fountains. They are very easy to make and they look and sound like a 2" starmine!
Of course, you will need some N/G black powder (pen fountain grade), a bottle cap, a pair of scissors, a pen, a spoon, masking tape, a piece of paper, and a fuse.
If you're an amateur pyrotechnic, this is a good firework to try out. Loads of fun, especially at night. Watch it sparkle up the night sky.
