I include an actual excerpt from the article.
Yes, I can do that. It's fair use and Nature and the others will be thrilled that more people are reading some of their material. It's sort of why they do this, to spread knowledge.
Now, get set for something weird:
"Counter-intuitive phenomena that arise in fluids under the action of vibration have attracted considerable research interest since the 1950's. For example, in a vibrating volume of fluid, gas bubbles cab sink and heavy particles can rise. Moreover, a layer of fluid can be levitated above a layer of air by shaking the system vertically at a relatively high frequency (of the order of 100 hertz or more). On page 48, Appfel, et al. report another remarkable phenomenon associated with a vibrated, levitated layer of fluid: objects can float upside down on the lower interface of the fluid, as if gravity were inverted."
The theory put forward about why gravity is inverted doesn't square with the theory explaining why you can levitate fluids in mid-air. The scientists are confused for now.
But you can use this technique to cleanse lead or other contaminates from water, as well as to create renewable energy, if scaled... plus, they're looking into how it can used for various medical treatments...
