Question

Would adding sulfur to the back powder or on top make any difference?

How do I make a firecracker with a loud audible component?

Community Answer

Get a small container and fill it with black powder, then make a hole in the top and CAREFULLY insert the firecracker. Stick the fuse through the hole on the top and close the lid.
