Cheap Airsoft Frag Grenades

This is my first instructable, so hang tight. This grenade is obscenely dangerous, and should only be attempted by professionals or people with little-to-no attachment to their various extremities. Okay, maybe I'm exaggerating a bit, but this thing could easily take off a few fingers if you handle it improperly. Also, the noise is near-deafening, so watch out!

Step 1: What You'll Need:

1 Key-Chain Ring
1 Pack Strike-On-Box Matches
1 Commercial-Grade Firework
50-200 Cheap Airsoft BBs
1 Toilet-Paper Tube
Scissors
Scotch Tape
Duck Tape

Step 2: Remove Striker Pads

Use the scissors to cut apart the match box and save the pads and top and bottom for later.

Step 3: Take Apart Firework

Use the scissors to carefully disassemble the firework, removing the warhead from the rocket. Cut the main fuse off the rocket, and then discard.

Step 4: Seal the Tube

Seal one end of the tube with duck tape.

Step 5:

Stuff a couple tissues or sheets of toilet paper down the tube.

Step 6:

Add about half of the BBs to the tube.

Step 7:

Bind all three fuses together with scotch tape.

Step 8:

Assemble the triggering mechanism by taping the two strikers facing each other over the clip, and looping the ring through the end.

Step 9:

Tape six matches around the fuses.

Step 10:

Put the whole explosive together. Note: This mechanism can also be employed to great effect with smoke bombs. Just substitute caramelized sugar and KNO3 for a firework and BBs.

Step 11:

Wrap the explosive loosely in tissue, and pack it in the tube on top of the BBs.

Step 12:

Fill it up almost to the top with BBs, then pack another tissue in on top for good measure.

Step 13:

Tape off the top, then decorate as you wish! Have fun fragging your friends and try not to blow off your hands! The blast radius is about 15-30m, and within 5, they will draw blood. Be careful!
