Step 1: Materials
The things you need can be made with the instructables on the site or found around the home. For one strike-anywhere firecracker-
-Black powder or flash powder
-Strip of paper 11in. by 1in.
-Inner ink holder of a pen
-Hot glue gun
-1in. of visco fuse with a diameter of 1mm-3mm
-Small funnel rolled from paper
-Strike anwhere match
Step 2: Construction
Roll the paper around the pencil as straight and tight as you can get it, then wrap masking tape around the whole length of it, but leave the ends open. Plug one of the ends with hot glue. Using your funnel, pour in you black powder or flash powder until it's almost full. Insert the fuse into the unplugged end of the firecracker until it goes slightly under the level of the powder. Use as little glue as you can to plug the air holes around the fuse, so you don't smother it. Finally, tape the strike-anywhere match so it touches the fuse and the white tip protrudes slightly higher then it. Your done! Now to light it :)
Step 3: Ignition
Strike against any rough surface and throw. These should be waterproof but I haven't tried it yet. Oh, and try not set anything on fire. These firecrackers make a bang when they ignite so dont light them in your ear please. Experiment with different sizes of paper and compacted powder to get louder reports. Have fun!
