[Nighthawkinlight]

@peterguy3 Less black powder lift.

This may be a stupid question for some people, but how do you launch it?

[Nighthawkinlight]

@SimonsRandomChannel Watch my most recent video about how ball shells work. This is fired from a mortar just like a ball shell.

did you prime your stars? and can you tell me what the best prime fo stars are.

Thanks!

[Nighthawkinlight]

@Anthony82949 Black powder works as prime for most stars. To light this I lit the fuse and dropped it down the gun, which is generally not considered a safe practice. I recommend you use quickmatch or enough visco that you can have the mine at the bottom of the gun and the fuse reaches to the top.

One tip. NEVER use a PVC tube! If the shell explodes in the tube it will shatter sending sharp pieces of PVC everywhere. Use a fiberglass, HDPE (High Density PolyEthylene) or heavy cardboard.

Do you make the stars or do you buy them?
