These Old English Beer Cans are Safe Places to Conceal Money. Since most burglars spend less than six minutes inside a victim's home, they only have time to check the most obvious places for valuables. These unique "safes" are safe places to conceal money and valuables inside a can of common Old English beer -- one of the last places a thief would think to look. According to the Chicago Police these units are better than a locked safe, a thousand times cheaper, and some of the most safe places to conceal money.
