Behold, the non-stick ketchup bottle! (video)

25 May 2012

A team of researchers at MIT have developed a substance that ensures the entire contents of any bottle or jar will slide right out, ending the shaking, squeezing and slapping frustrations of many.

Oh we’ve all been there: a fresh plate of chips in front of you, a splash of salt and vinegar if you like, but then you get out the ketchup bottle and what’s left of the sticky red sauce is clinging to the insides, never to reach your tastebuds.

Enter, LiquiGlide – and well-smacked bottle bottoms can breathe a sigh of relief.

LiquiGlide is a super-slippery coating for containers developed by the Varanais Research Group at MIT that finally lets you enjoy your sauces and dips right down to the last dollop. Video demonstrations show the coated bottles in action, and there’s something quite beautiful about how cleanly the condiment slips out. Not a drop wasted – befitting of these frugal times.

By the MIT team’s calculations, about 1m lbs (more than 450 tonnes) of food gets thrown out each year worldwide. This product could help to alleviate this waste and also cut down on the production of 25,000 tonnes of large petroleum-based plastic bottle caps that are used for ‘squeezy’ bottles (which aren’t nearly as effective as LiquiGlide-coated containers).

Fret not if ketchup is not your topping of choice as the team claims its creation works with every condiment they’ve tested so far, including mayonnaise, jam and mustard. And, so far the coating can be applied to all materials tested, including glass, plastic, metal and ceramic.
