Acoustic Levitator

Concepts Conveyed:

• This demo consists of a frame affixing 72 40kHz transducers in an arrangement that creates an acoustic focus region in which small particles can be suspended, and a power and control panel.

Instructions / Notes:

• To start, flip the red switch on the control panel.
• Use tweezers of fingers to drop small styrofoam particles into the central axis of the levitator.
  • Alternatively, lay the frame on its side, place the rag underneath, and use the eyedropper to drop small beads of colored water into the center axis of the levitator.
• When lifting, waving, and shaking the levitator, be mindful of the wires and hold a short length with your free hand to avoid yanking or tangling.

Demo Staff:

• Plug in the apparatus and ensure the switch is set to the off position before class
• Provide tweezers, several small pieces of styrofoam, an eye dropper with dyed water, and a rag.
