Introduction: Verry Simple Frag Grenades

Picture of Verry Simple Frag Grenades

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.

Step 2: Connecting the Connectors

Picture of Connecting the Connectors

simply clip the orange connectors onto the white one its verry simple.

Step 3: Youve Finished the Simple Frag!

it should look like this

sos i made an error with the yellow box thingys

Step 4: The Impact Frag

Picture of The Impact Frag

this it just the simple frag with a rubber band around it it strengthens it and therefore making it harder to smash so you can throw it harder.

first make the simple frag and get yourself an elastic band.

Step 5: Impact Frag Elastic Band Part1

first put your elastic band on like this

Step 6: Impact Frag Elastic Band Part 2

now this bit "can" be tricky. keeping the band on the first two orange connectors stretch it over the upper and lower connectors like this.

Step 7: Impact Frag Finished!

stretch the band over the remaining connectors.

Step 8: The Ball of Doom

you will need two of the blue circular connectors and eight red connectors.

Step 9: Ball of Doom Step 1

clip the two blue connectors togeather to make a ball.

Step 10: Ball of Doom Step 2

now clip on the red connectors like with the simple frag.

Step 11: Finished Ball of Doom

add the rest of the red connectors and it shoukd look like this

Step 12: How to Throw

Picture of How to Throw

to throw the simple frag grasp it by the centre of the white connector.

to throw the impact frag hold one of the orange connectors.

theese are both thrown like frisbies

to throw ball of doom hold in palm of hand and throw like a ball

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.

FeebleReaper (author)2009-08-24

hey, i posted a grenade similar to the ball of doom, and i gave you credit. check it out

JaymzFlipper (author)2009-06-12

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!?!?!

sebby38s (author)2009-03-31

The ball of doom works great!!!!!!!!!!

An Villain (author)2009-03-31

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.

tomcat955 (author)2009-03-13

how does the ball of doom work it dosent have eny rubberbands or enything

josh1324 (author)2009-02-25

the impact frag doesn't work at all. But the other one works pretty well! :-)

CrashMGD (author)2009-01-17

dont see how it will work

Russianbomb (author)2008-12-11

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

DJ Radio (author)2008-11-06

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........

mamoo (author)2007-09-16

DrWeird117 (author)mamoo2008-07-12

nicamo (author)2008-07-01

it doesn't explode but it's a good idea.

T.E.A. (author)2008-06-28

I_am_Canadian (author)2008-05-15

penguinskankill (author)2008-02-03

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

anarki121 (author)2008-01-26

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

the inventor (author)2007-04-30

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.

italiangold (author)2007-08-07

maybe cut out the middle of the blu part and weld the connecters to a pingpong ball filled with gun powder. hmmmm good instructable.

nkk07 (author)italiangold2007-11-27
