p.s. sorry for bluryness, the photos were taken with a webcam that was zoomed in alot.
Step 1: End Caps
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.
Step 2: Put It Together
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.
