Have you ever been angry because the tomato ketchup wouldn't come the bottle? Have you ever squeezed and squeezed the toothpaste tube but the last bit wouldn’t come ? Have you ever spent ages trying to scrape the last bits jam the sides the jar? If the answer to these questions is 'yes,' you may be happy to know that a solution to your problems is coming. Scientists have invented a super-slippery surface that can be put the inside bottles, tubes, jars, tins and other containers. The slippery inside means anything will just slide out, like water. Every last drop things like glue, paint and cosmetics will come , leaving the container totally empty, and making you happier and richer.

Scientists the Massachusetts Institute Technology and the company LiquiGlide wanted to create something that would reduce waste and save us money. The technology's co-inventor, Dr David Smith, said every day, millions litres ketchup, sauces, paint, gels and creams get stuck to the sides containers and are thrown . He said: "The technology has the potential to significantly reduce waste and be a big part the zero-waste economy." The LiquiGlide website says: "What the wheel was to transportation, LiquiGlide is to liquids - it changes the way liquids move….We want to revolutionize consumer packaging, reduce waste, and create efficiencies. We are motivated to save lives and improve the world."
