in regards to lift height...
my shells are the same weight,but it seems like the lift is going past the shell.i recovered one of the failed shells and the outside is black and it splashes upward like the pressure is going around the shell.all im using is a cardboard cylinder(about1in)wide by 3in tall.that is my shell.attached to the top of the shell is a smaller cylinder with the lift powder in it.this is then inserted in the tube upside down.blackmatch as the fuse.it seems like it fits tighter at the middle of the whole shell.maybe this is why.im going to add thickness to the main shell instead of the lift part.hopefully this will correct the situation!!!

please help!!!@! can anyone please tell me why i can send 1 shell up with no problem, then send another one up with the same lift and it just poofs out of the tube like i used meal powder instead of lift powder??
i cant figure this out!
its the same powder. im not changing anything. one will go boom and launch and the next will go poof and go about 8 feet. anyone help please??????

ive ordered many chemicals from ebay and paid with paypal.up to 10 pounds of kno3.havent had a knock on the door yet.

thats the way i made it but it doesnt work. it just sparks on the battery.the graphite tip doesnt even get warm. i took two pieces of wire and soldered them together,then dipped it slurry. but like i said it doesnt work????
