German scientists have solved the age-old problem of how to get the last globs of ketchup out of the bottle.

They have designed a special non-stick coating that when applied to the inside of the bottle allows the red sauce to slide out, rather than sticking, without leaving a drop behind.

It is anticipated that the first bottles could hit shop shelves within two to three years.

When thrown away up to 20% of foods like ketchup are left inside the bottle.
