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!

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.

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

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

Nice idea. I would like to try it but i have no ball, what set do you get them from?

Prranavan in reply to Mr TenaciousApr 10, 2009. 2:05 PM

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.
