I want to have an umbrella that changes its color once the rain starts falling on it. The umbrella will start out in black and white but each rain drop will change its color. When the rain stops and the umbrella dries the colorful design will slowly fade back to the primary color. I suppose some dyes which work if water is applied should be used for such an umbrella creation.

I find the idea to have Rain Level Boots exciting. They are both stylish and informative as they tell the wearer the various levels of rain that have fallen once the wearer steps in a puddle. They are cute and fun, adding some much needed flavor to the rain boot style.

My idea is to create a chain of clothes stores all around the world which all work like an international bank. You deposit will be your money in your city's store. If you want to travel to another country you don't need to take any clothes. When you arrive you take your clothes from bank clothes store, and when you leave you return them.

I'm a soccer player. It is a real disaster for me to have a game on a sunny day as I hardly see anything and often lose the ball. My idea is to create sunglasses that are contacts so as I could look into the sun and see the ball.

I suggest creating shoes with metal detectors for soldiers. The metal detector would be attached at the bottom of the shoe so as soldiers would be able to detect mines and trip wires in the field.
