Introduction: Knex Snapper ( Grenade)

About: I make youtube videos now and i don't make instructables at all anymore. I've been into RC for over 4 years now and have had a stampede vxl, E-Revo, savage flux 2350, savage xs, tamiya cc01, scx10's, a wraith,…
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)
