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.

Nice, I had had this Idea for a long time, but no spring that would work =(

i got mine from an old game cube turbo controler

Me too :( Only elastic bands.

If you have a spring donation then please post it to ..18 Sodsbury Terrace, Hooverhampton, Bingoland.

Bingoland, eh? Can't say I've ever heard of that place before.....

Ain't that where Muslims are supposed to face when they prey five times a day?

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

i thought of this when i was like 10.
