Mini Acoustic Levitator

The idea of levitating small items with sound waves is nothing new. Acoustic levitation can be achieved by using acoustic radiation pressure from high intensity sound waves to suspend matter in air. This mini acoustic levitation kit comes with everything you need to try it. It is plug & play and can be used to levitate one or multiple styrofoam pieces and even small insects.

As you can see in the above video, you can lift and tilt the device slightly without losing the effect. More information is available here.
