DrWeird117 (author)I_am_Canadian2009-04-30

tcorcoran39 (author)2008-03-31

are the green rods the tiny ones or the long ones?

DrWeird117 (author)tcorcoran392008-07-03

long, but u can also use red rods, but i used a crossbow bolt or a bamboo skewer.

sharlston (author)DrWeird1172009-04-30

what is a crossbow bolt?

DrWeird117 (author)sharlston2009-04-30

Ammunition for a crossbow.

sharlston (author)2009-04-30

i had the same idea but mine shoots bb bullets put if you pull it to far back the connector comes of and the rod shoots out

salbabob (author)2008-07-18

put the ammo through the green things, put the rubber band around the back, pull back and let go

CheezConquerer (author)2008-07-02

this thing rocks... 2 minutes to build , endless fun + pain!! move on to something else now

dan333 (author)2008-06-22

i got mine to go 39 feet!!!

therandomperson (author)2008-06-17

both of my mates made that in my street and i thought it was cool but you should move on and make machine guns and gatling guns

backyardpyro217 (author)2008-06-08

make it about 3 inches longer and its gonna be REALLY powerful, I've done crossbows in the past and I made one that makes you BLEED:0

Wow. I got a suggestion though. Pretty hard to do, bruised my right thumb, but replace the gray rods with yellow rods. And with the band, put 2 green rods on top of the rubber bands. really secured mine.

Sorry for double post, but if you want more power, change the 2 yellows that I said to red rods, the ones that connect the greens. Then, put on more greens.

I_am_Canadian (author)2008-02-11

I_am_Canadian (author)cooperboy2008-02-11

just put the ammo through the barrel, put the elastics on the back of the bullet, pull back and let go!

awsome (author)2008-02-01

AJ_DA_DJ (author)2008-01-30

Brill! good accuracy too, just missed my sisters head!

luis trixter (author)2008-01-17


luis trixter (author)2008-01-17

i really like it because its good for beginers like me and is easy to build but you need to get the instructions for shooting and loading ok

Squeaka (author)2008-01-06

Thanks for posting this

CoolJB (author)2007-12-07

hey while I was at my friends house i brought my knex and we stayed up late and he built this and when he fired it it couldnt go 24ft. XD

kiwi20 (author)2007-11-25

cool idea, one thing you could do is to put the unused amo in the brown connectors for storage

Jill 32 (author)2007-10-27

Just so you know, people HATE it when you say "This is my first instructable so go easy." or "First instructable, be nice". Just letting you know.....

wussap (author)2007-10-15

it doesnt even have a trigger, and 26ft is OK
