The Rain Umbrella
An umbrella is a folding dome on a stick that opens like a bird's wing. It is made of thick cloth that doesn't let water through, so the drops slide off it like down a slide. When it is open, it is wider than your outstretched arms and covers you like a little house. The wind can flip it inside out, but if you hold on tight, it will save you from a downpour.
