Wow this is really amazing! Simply place this mini beer glass in water and watch, over a period of 72 hours, as it grows to 600% from it's original size.
When removed from water it will slowly shrink back to its original size. It can then be grown again and again. A great gift for any beer drinker; it's cheap, it's good, it's gas-free - cheers!
This is a novelty item and not for consumption.
