Foam Gold Looks Like The Real Thing But Is 98 Percent Air
Swiss researchers used cutting-edge techniques to create a foam gold that's 98 percent air. How useful could this material be in the real world?By Ryan Biek | November 29, 2015
We all heard the legends as kids –– ships sunk from carrying too much gold, lending lessons in greed.
But Swiss researchers might have just made all those lessons obsolete after creating a foam made of genuine gold. It's so light, it can float on top of a cappuccino's foam.
The researchers published their discovery in the journal Advanced Materials. What they created is 1,000 times lighter than gold's usual form because it's 98 percent air.
