I could never get the one that uses strike anywhere matches to work so here is my method.
Materials:
1 Tennis ball
1 Knife or screwdriver
Explosive Comp.
Fuse 5in min
A lot of duct tape (you can use other tape but duct tape works best)
A Funnel
Step 1: Take the knife and cut a hole in the tennis ball about a centimeter or less in diameter. Step 2: Fill the ball 2/3 the way with flash. (this depends on what powder you are using)
Step 3: Place a piece of duct tape over the hole and wrap the ball in about 6-8 layers of duct tape, it's best if you wrap it very tightly.
Step 4: Take a nail and poke a small hole in the ball poke it so when you pull it out it has powder on it that's when you know it's far enough.
Step 5: Now add your fuse and light.
CAUTION: This is very loud and risky if in a suburb. Beware.
P.S. (optional)If you want it to be super loud add about15 layers of tape, I know it's a lot but it is worth it.
