Every 15 minutes, Americans insert over 3.5 million coins into vending machines. We'll visit a sprawling factory that mass produces the latest in high-tech vending machines, and a small company that makes a giant gumball machine that holds 40,000 gumballs. Then, there's the dreaded parking meter, including new ones that can take credit cards and text message for help when they are being robbed or vandalized. We'll visit America's last pinball factory, and see what strange coin operated fare kept people amused 100 years ago. Is coin counting Coinstar the ultimate coin operated machine? We'll follow their coins all the way to a Brinks warehouse. Our last stop is Marvin's Marvelous Mechanized Museum, housing some of the weirdest coin-op machines ever invented. If seeing a life-sized, robotic old man vomit is your idea of entertainment, drop a couple of quarters into "Dr. Ralph Bingenpurge". Now, that's money well spent.
