Is getting ketchup out the bottle difficult? Does the last bit of toothpaste stay in the tube? Does jam stick to the side of the jar? There is now an answer to these problems. Scientists made a very slippery surface for bottles, tubes and jars. Things like glue, paint and cosmetics slide out like water. This will make you a little richer.

Scientists from LiquiGlide made the surface to cut waste and save money. Millions of litres of ketchup, sauces, paint, gels and creams stay in containers. They are thrown away. The new surface will cut this waste. It is part of the zero-waste economy. LiquiGlide said the surface is important and helpful, like the wheel.
