Active Stubby Holder
An active stubby holder not only keeps your beer cold while been drank but actually makes it colder. The need for this is obvious to anyone who has had a beer on a hot summers day and noticed that it warms up halfway through drinking it. It also re-uses an old sock for its cover.
