Put away your spare change. The coin-operated vending machine is dead.

In its place? A tweet-operated beer machine that the Broncos will debut at Sports Authority Field at Mile High Stadium this Sunday.

This futuristic contraption only works when game-goers whip their mobile devices out and tweet using a specific hashtag. Only then will it dispense one of five magical gifts -- including a voucher for free beer.

Other gifts include seat upgrades, skis signed by former Broncos QB Jake Plummer, ski lift tickets, and team merchandise.

It seems like a pretty sweet deal -- until the first beer voucher gets stuck in the chute and fans try to tip it over.
