My task on this project was creating an automatic mechanism that would fire a dozen eggs at contestants on Silent Library.
I experimented with a tennis-ball-style launcher first, but settled on a gatling gun setup, powered by a disassembled t-shirt gun. The revolver chamber is made out of sections of PVC tubing ringed with UVA foam to prevent air from leaking out of the gun. A one-way mechanism rotates the revolving barrels to advance a new egg into place whenever the chicken cycles. A cable pulls on the gun’s trigger when the chicken is in the horizontal so that the eggs will fire out of the rear of the chicken at the right moment. Dario Gimenez sculpted the chicken-shaped cover for the machine.
Below is a video of the mechanism at work (with the air gun removed,) followed by a clip of the egg gun firing a few eggs at a contestant.
