The most waterproof material ever has been created by scientists in the US.
Lotus leaves were thought to be one of the most water-proof material in nature because water bounces off them quickly.
But engineers have made a new material that repels water up to 40% faster.
To make material waterproof you have to stop water sticking to it. The team found the best way to do this was to have microscopic ridges which break up the water as it hits the surface.
The new “super-hydrophobic” material could be used to keep clothes, tents and even planes dry.
