Simple K'nex Grenade by Bradley

Introduction: Simple K'nex Grenade by Bradley

In this Instructable, I will show you how to make a grenade from 2 halves of a knex ball(sold in the 250 piece set with 150 bonus parts, and maybe some others, but this is where I got it ), and a spring. I got mine in a nerf gun. Also, a red rod will be helpful.
Let's get started!

Step 1: Assemblance

The red rod is just here to help, you don't really need it, though it is fairly difficult without.
Also, shrapnel may be added, just put it vertically so All the shrapnel won't fall out of one of the halves, then press the two halves together.

Step 2: Done!

Wowie! We're done already! To detonate just throw it. Please don't be harsh. This is my first instructable, and I hope you like it!

    I have the perfect spring that would work :) I have no ball pieces, though :( I wish I did, I would go throw this at my brother right now.

    It is good but if you fill the inside of the ball with blue spacers and green rods, it will be a lot better

    you can get the ball pieces in the wind up motor set with a red small bin. theyre kinda easy to find so I think you wouldnt miss it in the toys section.

    I said in my intructable where to get the ball, It comes with the 250 piece set with 150 bonus pieces. I found that set on amazon.com for about 20 dollars.
