Many people prefer to use a bar of soap, rather than a liquid alternative.
If you have to share facilities with people you don’t know, today’s invention offers a way to ensure that the bar gets cleaned before you apply any soap to your body.
The soap is placed in a perforated tray beneath the flowing water. This helps ensure that any germs and skin cells of the previous user are washed away.
You could choose to wash the soap in this way and then use it as normal, or just stand under the water flowing over the surface of the bar.
