Introduction: Knex Snapper ( Grenade)
this is a knex snapper. i got the idea of of youtube but i thought you guys here on instructables might want to know how to build it. it is so easy to build that it is one step. (set it on a couch or around a corner of a hallway. those places work the best.)
Step 1: Make It
The last pic shows the blue rod on the tip of the gray rod with the rubberband over it. (your done)
