Found it!
I don't want to add this to my YT channel yet, so here's a dropbox link. I may remove it later, but you can download it by right clicking and selecting "save as" or something. . .

None of my rubber bands work, and I don't want to buy any. So for now, I'm not going to sue this grenade...

author
charge11595 (author)Renn6452012-12-29

Thats ok. It's been like 3 years since I made this instructable, and I've moved on since then, although I try to stay some what active on instructables. . .

Renn645 (author)2012-12-29

It's hard when I try to put the white rod in the third slot, it doesn't properly fit in. It kepps staying out. Bleergh, any solutions?

author
charge11595 (author)Renn6452012-12-29

It sticks out a little depending on the tension of the rubber bands. Perhaps try a tighter one to old the white rods, or a looser one underneath?

done it awesome time to test

author
trap freak (author)2010-03-05

it took me an hour and 1/2 to fill it ... i dont want to test it because i will have to build it all over again :D

author
charge11595 (author)trap freak2010-03-06

 Keep practicing! It should take no more than 5 minutes to build/ rebuild. Also, try my Fragmentation grenade, it's easier to build/rebuild.
BTW, the whole grenade should not fall apart, only the 4 gray and 4 white rods should.

 Did you see the video?

author
sci4me (author)charge115952010-01-30

yes, i tried to do it, but found it difficult. very difficult.

author
charge11595 (author)sci4me2010-01-31

 For me, that step is tedious, and fairly difficult. Please show me a video of your attempt, or explain with specific details.
Also, have you tried my fragmentation grenade? Another person may have a similar problem, so I might need to revise these instructables.

author
sci4me (author)charge115952010-01-31

how do i put a video on here?

author
charge11595 (author)sci4me2010-01-31

author
charge11595 (author)lemonpickle2010-01-12

 I know... Can you make it? If it is too hard, or you don't get enough "bang for your buck", I recommend I Am Canadian's war bomb.
