Waterproof clothes and windows
The British are often upset by the weather. However, there is a future for waterproof clothing. The water just jumps off the cloth.
A special chemical does the jumping effect. People use this chemical in house paint. For the first time, people spray the chemical on boots and a jacket. They use dirty water for testing. It really works!
People want to make this chemical stronger. They can use it for buildings and windows. When it rains, there is no dust on the glass or the buildings. We do not need to clean the windows. Everybody likes that!
Difficult words: upset (not happy), waterproof (something waterproof does not let water in), dust (very small pieces of dirt).
