"The essence of levitation technology is the countervailing of gravity. It is known that an ultrasound standing wave is capable of suspending small particles at its sound pressure nodes. The acoustic axis of the ultrasound beam…" OK, enough [science](https://www.hypebot.com/content/files/arxiv-org/ftp/arxiv/papers/1312/1312-4006.pdf). If you read Hypebot, you also (hopefully) love sound, and if you love sound, you'll love watching what it can do:
