This instructable will teach you how to make a K'nex grenade that MIGHT have the most fragments on this site! (59 fragments!) It's very easy to make and it's very powerful for its size!

Step 1: Pieces

You will need...

White connector x 3

Yellow connector x 8

Orange connector x 16

Red connector x 16

Gray connector x 16

Rubber Band x 2-4 (4 for best power)

Step 2: Building the Grenade

First, take a white connector and attach 8 yellow connectors to it without any rods like so (pic 1). Then, take 8 Gray connectors and attach them to the yellow connectors, skipping a yellow connector every time because they don't fit otherwise (pic 2). Next, attach two orange connectors to each yellow connector without any rods (pic 3). Then, attach 8 red connectors to each white connector (not the one on the grenade)(pic 4). Next, attach a gray connector to every other red connector like so (pic 5). Finally, put them together and you're done (pic 6)!

Step 3: Adding Power (optional)

This step is optional, the grenade still works without rubber bands. if you want to add power, put 2-4 rubber bands around the grenade longways. Ta-Da! Please comment and rate! Suggestions appreciated, they're what got me to build this!

Step 4: In Action!

Watch this video of the explosion! This is only using two weak rubber bands!!! (all the pieces went into the corner because that's the way i threw it.)
