One for the impatient coffee-holic, Shower Shock caffeinated soap delivers a morning caffeine fix as you shower. Each bar contains 1250 milligrams of caffeine - enough for 10 doses according to manufacturers Think Geek - that is absorbed through the skin as you bathe normally. The peppermint scented soap itself is vegetable based and doesn't contain harsh ingredients like ethanol. Shower Shock is available online at www.thinkgeek.com for US$6.99 per bar.
