Technic 20: A Single Shot Launcher Made Out Of Lego (Blaster)

Hey guys. Today I'm going to show you my latest build "Technic 20". It's a single shot blaster. It uses 4 rubber bands; 3 for shooting, 1 for trigger return. Main body and trigger mechanism is made out of Lego technic pieces, the barrel is paper and the plunger is a pen. It shoots technic pins up to 30 feet. I am very pleasure with this thing and its power.

Thanks for reading and see you next time. :)
