Hi everyone:

Has anyone tried using the an ultrasonic transducer (from an ultrasonic cleaner) to make things levitate? Here is an interesting demo on youtube: https://www.youtube.com/watch?v=qy1w6rTpC2g I was also tipped off about such a levitating device on kickstarter: https://www.kickstarter.com/projects...nce-of/updates

It seems to have the same part from an ultrasonic cleaner like this one: AC110V 100W 40K Ultrasonic Cleaner Power Driver Board 1pcs 60W 40K Transducer | eBay Unfortunately, this type of ultrasonic transducer may cause hearing damage when operating in the open, but it could have some possible uses in an "antigravity device".
