Introduction: Knex Grenade (Fragmentation)

A knex grenade with a working pin.
Pros:
-Small, easy to conceal.
-Has a working pin.
-Nearly impossible for it to explode in your hand, unless you remove the pin.
-Easy to use.
Cons:
-Has a small chance to not explode when thrown.
-Somewhat hard to build/rebuild.

Step 1: Materials

Gather the following pieces:
1 rubber band
Rods:
-6 white
-3 blue (One is missing in the pic)
Connectors:
-1 white
-1 blue
-6 dark gray (optional)

Step 3: Step 2

Step 4: Step 3

Assemble the body of the grenade

Step 5: Step 4 (Optional)

Remove lid and insert gray connectors.
Then replace lid.

Step 6: Step 5

Practice building this grenade (or modify it) so you can build it without referring to this instructable!.

Step 7: How It Works

1) Removing the pin allows the rubber band to move.
2) Sudden movement (like hitting the floor) releases the rubber band, allowing the fragments to fly off.

Step 8: How to Use

1) Make sure that target is within range.
2) Remove pin.
3) Throw.
It may explode in your hand if you remove the pin, and wait before throwing.

    Wow, I've an amazing idea :D
    Put a rope on the firing pin, thorw your grenade away, hold the rope and the grenade will explode far away (unless you rope is short)!!

    Oh... I think i understand your problem now. Try using a smaller rubber band. If that doesn't work try to send me a picture.

     Maybe...
    The problem could also be that you didn't wrap the grenade with the rubber band correctly
