Pros: More powerful than a pistol
Looks more impressive
Shoots further
Can shoot rubber bands and ammo or just rubber bands.
Cons: Hard to hide
Barrel bends slightly
Rubber bands are stretched nearly to their breaking point, so they snap after few shots
Slow to reload
Awkward firing









































It should be strengthened in the barrel, and called 'Knex Paper Plane launcher' or something to that effect. If you were to, though, make sure the band doesn't fly off with it!
I'm working on how to keep the rubber band on the gun for more power, because I've already lost one attached to an airplane in a tree.
