I use a small ultrasonic jewelry cleaner to wash old machine parts, and it's amazing watching decades of grease just mist away into liquid clouds. But the size of the machine's tub limits what I can put in there.

Then the object can be dropped into any vessel, like a bowl or even a kitchen sink, and turn the entire thing into an ultrasonic bath:

It's pretty brilliant, which is why it's become a crowdfunding smash: At press time the Sonic Soak had racked up $514,076 in pledges on a measly $10,000 goal. Buy-in starts at $230, and the developers estimate they'll have these ready to ship in December.
