Introduction: Knex Grenade

Picture of Knex Grenade

A knex Grenade that can be lobbed and detonates apon impact shooting bullets randomly in multiple diriections

Step 1: Building the Body

Picture of Building the Body

Build what is shown in the picture then add the firing bar and put rubberbands on it.
Make sure you have the rubberbands in the right place so they create the tension that holds the bullets in.

Step 2: Loading and Firing

Picture of Loading and Firing

To load it first pull the firing bar back. Take the square knex pice and stick the tip of the middle red connector into the path of the firing bar, stopping it from firing.
Add 2 green pellets per gap.
Grab by the firing bar and lob the grenade. The square falls out of place apon inpact causing the firing bar to be released. It shoots firing out the green pellets in random diriections.

You never posted?

bighead5454 (author)2008-12-19

pretty cool looking but i am new so i probly cant build it but one day i will I WILL

mettaurlover (author)bighead54542009-01-04

you can make anything regardless of your experience; that's what instructables is about: making it so that with the right supplies, anyone can make anything.

bighead5454 (author)mettaurlover2009-08-23

i know but besides now i am a lot better at building with few instructions so yeah

mettaurlover (author)bighead54542009-08-23

I can, technically, build just about anything from a couple external pictures of it. My gun is so simple that anyone could build it from just the intro pic; I just gave it steps so 'ibles would be happy with it. BTW, my gun IS pretty good, so why not build it? At the size shown, it makes a decent sidearm or a main gun, depending on your preference; I made a couple of much smaller ones that fit easily in pockets, but they can also be made much longer for other uses, such as sniping, but you have to remember to add one RB to the chain for every four sections you add on.

so can i but might need a few angles pics as well to see a glimpse of the inside i once build an SMG from thatt way took me literelly 4 hours

mettaurlover (author)bighead54542009-08-24

i only need pics of the inside for really complicated stuff.

fib3roptix (author)2009-04-14

Wow why waste this much time building the grenade that blows up in like 2 seconds

This is only the base. It is reusable, as far as I can tell.

woodfish (author)2009-05-29

cool but it blows up so soon

chopstx (author)2009-04-03

yeah, i don't understand this step. add more pics or steps. i would prefer steps

Wafflicious (author)2008-12-03

if i know im about to get hit in an elimanation knex war and i still have a team-mate i just run out with this and pull the pin laughing

Wafflicious (author)Wafflicious2008-12-03

(it stinks to throw as others will get the grenaid after. also if u tape on a wall near the door you can rig it to open fire when the door is opend. =)

anirox (author)2008-04-20

cool,but call it a knex fragmentation grenade

das94 (author)anirox2008-11-16

well, its not really a frag grenade because a frag grenade fragments, this one doesnt. Great instructable, I understood the directions (although a newcomer to knex probably wouldnt) check out my lego gun FTW

bomb voyajue (author)2008-11-14

put more steps

coolnamehere (author)2008-10-23

Looks great but as there is almost NO instructions on how to build it, i don't have a hope of actually building it.

the-ruler-of-craziness (author)2008-10-15

this is the only granade on this site wat scares me it cud go off at an any time so if it gets thrown at you theres only 1 thing you can do n thts take the pain rather tht or u can run at 1000mph

robocrazy155 (author)2008-07-17

Very powerful, kinda scary if it goes off ANYWHERE NEAR YOU, but it could use more instructions, but otherwise awesome.

knex0123 (author)2008-07-15

you should add more steps so people who look at this can understand how to build it.

I_am_Canadian (author)2008-05-27

Erm, Frogotten One? I think you mean Forgotten One. :-p

DrWeird117 (author)I_am_Canadian2008-07-03

lol, frogotten one...

T3hpw9ag3 (author)2008-04-10

Cool, but it needs more instruction

fobblewabble (author)2008-04-01

looks cool

I_am_Canadian (author)2008-03-31
