worked better than i imagined...and still with nothing more than fuse, paper, tape, and glue. thanks to Nighthawkinlight i used his tutorial for the general building of the shell but replaced everything with fuse! lift- 1/8" visco cut up in the bottom of the tube burst- powder out of 3 3" long 1/8" visco sticks insert-cut pieces of 1/8" red crackling fuse took pretty long to make because i had to cut a lot of fuse...but it was well worth it!!!
