Picture of verry simple frag grenades
C:\WINDOWS\Desktop\Stuart\instructables\Img0035\ball of doom finished.jpg
this is exactly the same as the first ones i made but the pictures work.

oh and yes for some reason this instructable has also been posted on another site if you look at it its still mine its got by the inventor on it.


theese are based on some frags i saw on this site but i cant remember who did them so thanks for the idea.
there are three: the simple frag, the impact frag and the ball of doom.

Step 1: The simple frag

Picture of the simple frag
first you will need 8 orange connectors and one white circular connector.

i can't believe it, i posted these things ages ago and recently I've started to receive tons of comments on them. Thanks everyone, but unfortunately i wont reply to most of them and i doubt i will be posting anymore Instructables. If i did though i think id make a new profile, because i don't make anything out of knex anymore. But once again thanks guys and maybe ill post some new things when i get the time.
hey, i posted a grenade similar to the ball of doom, and i gave you credit. check it out

I LOVE the ball of doom. But there's only 1 PROBLEM, Whenever I throw it all the fragments come back to hit me instead of hitting whoever is in front of me!!!! Can anyone tell me why this is happening!?!?!

in my opinion knex grenades are separated into two classes the first is rubber band powered "snap" grenades which have a bigger blast radius but usually less fragmentation and usually fire spacers the other kind are collapse grenades which have a smaller blast radius but usually fire pieces. the ones on this instructable are collapse grenades.

i dont see how an extremely durable grenade that has a 50% chance of exploding is useful. Unless your playing RUSSIAN roulette with a frisbee

Hey, I came up with a grenade with the exact design as this, without looking at yours. I checked to see if I was plagiarizing before i made a forum about it, and i found this.

5* for having my mind........

These are great!I like them a lot.
i built this. i took it to school and chucked at my teacher. i got in tourble and now i have detention for a week.

Wow... That must suck.
That sucks...
the Ball of Doom is awesome, i threw it @ my wall it went cross my room! The impact and simple gernade? not so much.

if the blast radius is'nt that big, its so easy to make and compact, you can throw 5 of those

when i was about to throw the ball of doom at them "> the head teacher came around the corner so i slammed it on the floor and ran they went about 5 meter radius! no one caught me lol.
