Lego elastic shooter

This Lego elastic shooter can can be fired repeatedly without any reloading. I made a strong mechanism that lets the big gear spin one rotation firing one elastic band, every time the trigger is pulled.

The black circle is the firing gear and the red gear is the trigger.
  

This elastic shooter shoots elastic bands accurately so I made some targets to shoot at.
I made this elastic shooter not strong but to test new mechanisms for more elastic shooters later.
