The world’s smallest boat has been made and it is small enough to fit on a human hair.
Named ‘Benchy the Tugboat’ the boat is super small and has been made by researchers at Leiden University.
They are trying to understand how small particles called ‘microswimmers’ move in water and reckon this miniature design could be just the tool they need.
To help observe these natural particles scientists decided to make their own microswimmer. They used a boat design that is often used to test 3D printers.
The tiny boat is 30 micrometres long from front to back, which is about a third of the thickness of a human hair.
It doesn’t have a propeller and can float on its own thanks to its realistic and detailed micro-printing.
