(Alba Adriatica, Italy) -- The world's biggest collection of Pepsi cans keeps getting bigger. An Italian named Christian Cavaletti originally earned the Guinness World Record in 2004 when his collection was just under 43-hundred. Today, it's almost three times that size. Guinness has verified his Pepsi can collection at more than 12-thousand-400. Cavaletti says the cans are from more than 80 countries and the oldest dates from 1948, the first year Pepsi came in a can. The 52-year-old site manager for a textile company plans to turn the collection in his basement into a mini-museum.
