I guess I need slower powder?

This was an 8 fold “jumping jack”. They go too danged fast! Or, maybe it’s a construction issue? Anyone made these with success before?

I can't say for sure, but it looks like you need to slow down the burn rate a bit. Strengthening the construction might work, but they are already jumping just fine! I wouldn't want to get hit in the jewels by something jumping around faster :D
