Just a lot of fun and works as advertised

Everything you need is included, even a wall wart power supply, the Styrofoam and a little spoon to put it in the acoustic field. It works exactly as described and shown in the video. However, it takes a little practice to get the bit of Styrofoam to exactly where it will levitate. That's part of the fun and when you get it there, along with two or three, it's a joyful experience. It's all well made too. It would be nice (but possibly not safe) if there was a bigger one.

STEM Toy Review

I bought a couple of these standing wave demonstrators for my great grandchildren. They worked perfectly out-of-the-box. The kids are aged from 5-9. They were intrigued by the levitating styrofoam with lots of questions. Kudos to the designers..

Works out of the box

The levitation effect was apparent as soon as the device was powered. There were no adjustments required. Small pieces of styrofoam were suspended immediately. I got up to three suspended at different nodes. The demonstration is small and difficult to display to more than one person at a time, though. Beware of drafts too.
