Cell Phone Flask

On the outside it looks like an ordinary (old-school) cell phone; unscrew the antenna and oh my gosh--you can fill it up with your favorite 4-ounce beverage! Made of stainless steel and about five inches long, it comes with a leather belt holster for those on-the-go moments. X-Treme Geek.com sells the Cell Phone Flask for $12.97, certanly the best gift for that geek with a social life friend of yours ;)
