Shower Shock is a bar of soap that has been impregnated with caffeine. The manufacturer ThinkGeek claims that when the soap is used, caffeine is exuded in the lather, to be absorbed through the user's skin. However, the idea that caffeine passes rapidly through the skin is unproven, and it has been suggested that the amount absorbed is not significant compared to a cup of coffee. Anecdotal accounts of using this soap also suggest that it is not effective as a delivery method for caffeine.
