Has getting tomato ketchup out the bottle made you angry? Have you ever squeezed the toothpaste tube but the last bit wouldn’t come out? Have you ever spent ages trying to get jam off the sides of the jar? If the answer is 'yes,' you may be happy to know that a solution to your problems is coming. Scientists have invented a very slippery surface for the inside of bottles, tubes, jars, tins and other containers. The slippery surface means anything will slide out like water. Every last drop of things like glue, paint and cosmetics will come out. The container will be totally empty, and you will be richer.

Scientists from MIT and the company LiquiGlide created the surface to reduce waste and save money. The co-inventor said every day, millions of litres of ketchup, sauces, paint, gels and creams stick to the sides of containers and are thrown away. He said: "The technology has the potential to significantly reduce waste" and be a big part of the zero-waste economy. The company website says LiquiGlide changes the way liquids move, like the wheel changed transport. It said: "We want to revolutionize consumer packaging, reduce waste, and create efficiencies…to improve the world."
