A fake vibrating bar of soap promises to hand-wash your clothes for you

The creators of the Dolfi want their little contraption to do most of the work for you, passively scrubbing clothes clean using ultrasonic vibrations while you relax on a beach.

Dolfi requires you to use a detergent because its cleaning power actually comes from an ultrasonic transducer inside that creates incredibly subtle vibrations in a sink full of water. Those vibrations in turn produce very tiny bubbles, Dolfi’s creators claim, that agitate a garment with enough force to dislodge dirt and grime as its broken down by a detergent.

Using the Dolfi is as simple as plugging it into an outlet and tossing it into a sink filled with warm water (power cord should be extra sealed and insulated), detergent, and a garment that needs cleaning. It needs about half an hour to sufficiently clean your clothing, after which you need to rinse and hang. So it’s not quite as easy as using a washer and dryer, but try packing those in your carry-on bag. Unfortunately at this point, the product only exists as a prototype.
