You can stop smacking the bottom of the bottle. MIT researchers have solved one of the world’s eternal scientific mysteries — how to get out the last drop of ketchup.

Their solution is LiquiGlide, a super-slippery coating that won’t let anything stick to the insides of glass and plastic bottles.

PhD candidate Dave Smith and a team of mechanical engineers and nano-technologists at the Varanasi Research Group have been working for the last two months developing LiquiGlide, the coating made of nontoxic materials that can be used in food packaging.

Smith, quoted in Co.Exist on Fast Company, said the coating could reduce food waste in a big way.
