Wow this grow your own birthday cake really is amazing! Simply place this mini birthday cake in water and watch, over a period of 72 hours, as it expands 600% from it's original size. It looks delicious, but contains no calories or mess to clean up afterwards!
When removed from water it will slowly shrink back to its original size. It can then be grown again and again!!
This is a novelty item and not for consumption.
