Trick Flip-Flops- a K'nex Ball Machine Element

These are instructions for one of my ball machine elements called Trick Flip-Flops. It looks like an element containing normal flip-flops. However, I call it Trick Flip-Flops because the flip-flops are weighted on one side and go back into place once triggered by a ball. Below is the parts list:
