Physics is a lot of fun, especially when you learn to do neat things like levitating water droplets. The LeviZen is an elegant acoustic levitation system that floats liquids in mid air. It has a walnut wood and machined aluminum construction. It uses sound waves not audible to our ears to levitate water droplets.
The device comes with two spot LEDs in its base to make the droplet glow. Pretty neat, don’t you think?
