Scientists & researches at the Northwestern Polytechnical University in Xi'an, China have successfully levitated ants, beetles, spiders, ladybugs, bees, tadpoles and fish.
some of these were levitated to a third of an inch into midair,
The technology used was an Ultrasound emitter, producing 20-millimeter wavelength sounds, that in theory - and now in practice, should be able to levitate objects up to half that wavelength.
the main focus for the research is to discover ways to develop alloys to pharmaceuticals without containers, enabling much easier manufacturing of materials that could react with containers or are too corrosive.
how long will it be until it becomes commonplace? and better yet how long till it works on people?
