Recently, I have discovered some unexpected functions of the gun. Turns out it can still cause damage when you are out of ammo. Well, not by hitting a guy's head with it, but by loading the rubber band onto the hook, stick the gun to the skin and fire "blank". It feels pretty much like being pinched hardly mixed with taking an injection.
Another function is brick shooting. I figured out it can do that when I build it, but I have no idea it's so powerful. A video showing the gun punching a hole on A4 size paper will come soon. So stay tuned! And don't forget to notify me via comments on this page when you successfully made this gun!
Hmmm...Your gun is a bit more smooth runing then mine because the rubberband is at the top. but it's like I thought, mine has a bit more power cuz my launchingband spans a bigger distance. But my version doesn't always shoot unless you do special things to it like push the tweeter all the way down and stuff like that.
