Mornings Have Never Been So Invigorating
Tired of waking up and having to wait for your morning java to brew? Are you one of those groggy early morning types that just needs that extra kick? Know any programmers who dont regularly bathe and need some special motivation? Introducing Shower Shock, the caffeinated soap from ThinkGeek...
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...
Have smelly co-workers that sleep in too much? Give them the gift of Shower Shock...

Great for the all-nighters and the people who need to be coherent for 8 am class... and as an added bonus: no calories or fat!
