Antibacterial soap company Lifebuoy have created a gadget to eliminate the dangers of bacteria found on supermarket shopping trolleys.
A refillable disk attaches to the trolley handle bar and can be swiped along it to apply a thin layer of sanitiser liquid, killing 99.9% of bacteria, making the trolley handles more hygienic and less likely to spread germs.
Together with Geometry Global Lifebuoy are looking into expanding the product for use in other public spaces and even hospitals. Great idea.
