This is my Knex war bomb/explosive/grenade. As the name suggests, this is made For knex wars. It does not blow up in your face while you are making it, explodes violently and sends a lot of knex flying in many directions. Be sure to check out the video below to see it in action. I also added a video of me shooting it with a gun. Enjoy!

Step 1: Collect Pieces

The piece count for one bomb is:
8 Rubber bands. I used ones that were slightly smaller and thinner than #64 elastics, the standard thick ones.
great bomb, I have enough knex, but i am using them for other projects
Well thanks and good luck when you do try it!
<p>where to get the rubber bands!?</p>
<p>You can generally find rubberbands at your friendly office store or sometimes even the office section of a grocery store! (So THAT'S why they exist... hmm... XD)</p>
It was great, but it hurt when i sat on it. Then i took an arrow to the knee <br>Lol
Yeah, dont sit on it.
yeah... my sister knocked it off our coffee table where I set it and it went off then she screamed at me. ;)
Note to all builders of this epic device: do NOT put a rod down the center, secure it, then fire it from a gun using a rod to propel the ammo. The force makes it explode in the barrel.<br><br>Personal Experience.
Yeah. Had a little modded rifle (converted to pistol) that I secured about ten to fifteen bands of varying shape/sizes to. After a few hours, and a few broken grey rods later, I got it to work with all the bands attached. Of course, I wasn't thinking that all the pieces of this 'nade are in delicate balance, so I shoved the rod in the barrel and pulled the trigger. <br> <br>Not a pleasant experience, and I'll just leave it at that.
i added a wire to it, and made a trip mine. I used it in a war that me and a friend had: i had a ton of traps, including the sipriani rifle v.3 <br>:D i think he still remembers. <br>
Sounds awesome :-D
This is the mega knex war bomb.
That's pretty dang legit :-D
i cant even build this thing without it going off before i finish building.
Practice :-)
theyre called 32 size rubber bands
na theyre size 31
They were larger that 32's but smaller than 64's... They were non-standard if I remember correctly.
33 maybe? or maybe your right and they were nin standard
I really have no idea what they were to be honest.<br><br>Rainbow colored, too.
ok then
hah thats one of the ways I put those together :)<br>It's very good, it mostly shoots shrapnel from out the top and bottom (left and right if hitting the floor), very directional. It's epic :)
Cheers :-)
I combined it with ikedog1995 landmine and it shot it up to chest height and then exploded. :D<br>
How do you build this? Everytime I try to build a segment, the thing explodes. I try to put a finished one down but it explodes. I tried 20 times already and failed at all of them.
ik vind het ook maar moeilijk<br>
that took of some of my skin the blue rod
i made it but wen i was trying to rebiuld it it almost hit my mother in the face
You have to watch out for that :-)
Just the thing to shoot with my brand new striker pistol! :D<br><br><br>Instantly , that reminds me of FPSRussia shooting explosives, heard of him?
Cheers :-)<br><br>And I've never head of FPSwhatever it is.
CONGRADULATONS YOU HAVE BEEN SELECTED TO BE BLOWN UP <br>┌&cap;┐have a nice day plz<br>oh and nice grenade i had a big mess to clean up but nice
it is so hard to make
It actually isn't if you have the right rubberbands. It takes time to make but it isn't very hard. (my pics)
Practice makes perfect :-)
&nbsp;I Found a typo! on step 3 look at how you spelled friends.. lol
Oh hush. <br /> <br /> :-p<br />
&nbsp;I will not be hushed!

Nay, only yellows work.
