Whatever floats your boat? Scientists defy gravity with levitating liquid – The Guardian

Scientists have turned the world upside down with a curious quirk of physics that allowed them to float toy boats the wrong way up beneath a levitating body of liquid.
In a striking demonstration of the mind-bending effect, the boats seem to defy the laws of gravity as they bob about on the water above them with their sails pointing down.
The bizarre phenomenon makes for a nifty trick, but researchers say the finding may have practical implications, from mineral processing to separating waste …
