YOU NEVER QUITE HAVE THE RIGHT COINS

FOR THE SNACK YOU WANT.

HOW DOES THE MACHINE KNOW TO SEND BACK ANYTHING FAKE

AND KEEP TRACK OF HOW MUCH YOU'VE PAID?

THE MACHINE DECIPHERS COINS WITH PINPOINT ACCURACY.

LIGHT SENSORS MEASURE THE SIZE,

AND ELECTROMAGNETS DETECT THE METAL TYPE,

IDENTIFYING THE COINS IN SPLIT SECONDS

AND SORTING THEM INTO COLUMNS,

DIVERTING FAKES TO THE REJECT CHUTE.

WHEN CHANGE IS DUE,

THE COLUMNS CAREFULLY RELEASE ONE COIN AT A TIME...

...TUMBLING INTO THE CHUTE.

THESE 85 PARTS WORK TOGETHER

TO COUNT 15,000 COINS A YEAR

AND RELEASE YOUR SNACK AT THE TOUCH OF A BUTTON.

BUT WHEN YOU'RE HUNGRY,

THERE'S NOTHING MORE FRUSTRATING THAN YOUR SNACK GETTING STUCK.

HOW DO TODAY'S GENERATION OF VENDING MACHINES

MAKE SURE YOU GET YOUR TREAT EVERY TIME?

HIDDEN BEHIND THE KEYS,

A COMPUTER ORDERS 1 OF 32 MATCHBOX-SIZED MOTORS...

...TO TURN THE SPIRAL 360 DEGREES.

AS THE SNACK FALLS,

IT BREAKS A LINE OF 10 INFRARED BEAMS.

IF NOTHING CROSSES THE BEAMS,

THE COMPUTER MAKES THE COILS TURN AGAIN.

WITH THIS INGENIOUS TECHNOLOGY, YOU'LL ALWAYS GET YOUR SNACK

AND NEVER LEAVE HUNGRY.
