A dangerous weapon! Just kidding. But it is dangerous.

Step 1: Gather Supplies

hammer
steel wool
matches
nail
duct tape
hair dryer
piece of pipe
stick
lead
and a scissor.

Step 2: Hammer the Nail Into the Pipe.

Move the nail around to make the hole slightly bigger.

Step 3: Take Out the Nail, Insert the Steel Wool, and Replace the Nail

Step 4: Now Position the Stick, Pipe, and Hair Dryer in Place As Shown

Step 5: Duct Tape the Whole Thing Together.

Caution: duct tape is powerful stuff.

Step 6: Light the Steel Wool Inside the Pipe.

Remember to use the lead, so that you can use the spark gun outside!

Step 7: Let the Sparks Fly!

Caution! Caution! Caution! Not to do without adult supervision. My pipe started melting at the end, so be extremely careful. Be sure not to point the gun up, otherwise sparks may go into the hair dryer, and we wouldn't won't that. Don't point towards any flammable objects and also not any human or animal!

Please be careful and rather not try this at home. It's not that useful.
