Knex Twist Grenade

Hey guys this is my first instructable! The new grenade i made has two versions. This grenade is not rubberband opperated, but does use them. I hope you like it, and credits go to KILLERK for the idea i used for my end caps.
p.s. sorry for bluryness, the photos were taken with a webcam that was zoomed in alot.

these are the ends of the grenade. if you have broken rods it is easier to slide them in on the last one or two grooves on the white connector. (see pics) also on the big one the rubberbands are #64s. i dont know what kind they are on the small one.

this is the last step, and all you have to do is put the parts together. slip the rod under the rubberband and insert the flat/round top of the rod into the crevas of the connector. you will know what i mean in the pictures.

you have just finished building yourself my grenade. now go use it what it was made for, and chuck it somewhere. there will be a video once i figure out how to upload it.
