Hi everybody !
I make firework since few years actually and sucessfull many stuff.
Actually i work about the stuff who made sound, i can build whistle insert but i have some problem for.... Hummer ! lol
Hummer is really basic and i don't understand why i can make them and be sure than they work goood...
I have build hummer who success but i make so hummer who is explod instead of make song.
My hummer explod : then end plug go out or the paper tube broke
I make hummer like this : BP same grade of milling than BP lift, rammed in paper tube with bentonite plug rammed by a hammer
I have try many size of hole where the BP ignite need to escape to make this strange and really cool song and i have try to mke tube with a bigger resistance and i have consolidated my bentonite end plug with paper wrapped on the tube.
So why my hummer explod some times ?..
