The ‘ketchup problem’ could be solved with ‘magic’ bottle

It’s one of the thorniest scientific problems facing mankind – how to get ketchup out of the bottle without either smashing it or swearing.

But now MIT scientists might have solved it – and the solution is going on sale.

Scientists at Massachusetts Institute of Technology (MIT) say that the secret isn’t wiggling the bottle in some mysterious way – it’s a new coating, which makes bottle interiors slippery.

The coating is slick, like an oily floor – and is so slippery that liquids slide out without leaving a trace.

Bottles using the technology are already on sale in Norway.

The researchers say that it could also work on toothpaste, cosmetics and even super-sticky substances such as glue.

The container is coated inside with a rough surface – then it’s coated with a thin solid layer, and then finally a liquid layer which fills in the troughs.
