We've all been there: Banging the back of a glass ketchup bottle, begging it to give you a dollop of the good stuff or battling with a plastic bottle coercing it into giving up the last of its contents.

Maybe that will be a thing of the past.

Six MIT researchers say they've solved that problem as part of an entrepreneurship competition. The result is a bottle coated with "LiquiGlide," a non-toxic material so slippery that the ketchup or for that matter mayonaisse just glids out when you turn it over.
