ThinkGeek is selling Shower Sock ($6.99/bar), a transdermal caffeine delivery system embedded in a bar of soap. Invigorating showers ahoy!
Shower Shock is an all vegetable based glycerine soap which does *not* contain any harsh ingredients like ethanol, diethanolamine, polyethylene glycol or cocyl isethionate. So it's a gently envigorating soap ;) Scented with peppermint oil and infused with caffeine anhydrous, each bar of Shower shock contains approximately 10 servings/showers per 4 ounce bar with 250 milligrams of caffeine per serving. No, we're not kidding and no you don't eat it. The caffeine is absorbed through the skin…
(Thanks, Songdog!)
