The VapoShower Effect
The cooling effect produced by Vicks VapoRub can be used to create a fantastic shower experience. Dissolve a few spoons of Vicks in water and let it freeze in an ice tray. Simply place a few cubes on the shower floor during your cleansing regimen and let the warm water melt them.
There is also the Vicks Vaposhower tablet which, according to their website, turns your shower into a sauna experience. The VapoShower contains a blend of eucalyptus and essential oils.
