Designer Nathalie Staempfli has come up with a pair of cool new soap dispensers called Soap Flakes that use regular bars of soap instead of liquid soap. The first attaches to the wall in your bathroom and looks like a traditional liquid soap dispenser, but when you place your hand underneath and push in the lever, it grates a bar of soap into little flakes that easily dissolve into lather while scrubbing your hands with water. The other version is more reminiscent of a liquid body soap dispenser for the shower. Just turn the base like a pepper mill and it grates and dispenses soap flakes from the bottom. Unfortunately, these are just concept designs, but perhaps with enough interest, they can be put into production. Such a cool idea.
