Imagine an umbrella with no canopy, but use air instead. The barrier between you and the raindrops is a sheet of steady air that is blown out by this hollow pipe.
How does it work?
The power of the air pushed through can be manually adjusted according to how heavy the rain is. You can control the length of the stick and the size of the air canopy. You also don’t need to worry about carrying a dripping wet object around indoors.
I really like this concept, although I don’t know much about physics and engineering. But when you see these instructions downside I know you’ll also be convinced.
