There are many useful inventions in the world. Do you want to have an umbrella that makes your hands free? Alan Kaufman has thought up the “Nubrella”, which means “new”+ “umbrella”. It is the first truly hands-free umbrella in the world.
One cool feature of the Nubrella is that you don’t hold it like a usual umbrella, you can wear it. The shoulder straps(肩带) of the Nubrella allow people to be hands-free, so when walking in the rain with the Nubrella, you are able to use your cell phone or drink a hot cup of coffee. Also, the Nubrella is safer than traditional ones and will never be inverted(颠倒) in the wind.
The idea for the invention began on one rainy day. Mr. Kaufman was standing in his shop amd began to look at people’s umbrellas. He found that they had to try very hard to keep their umbrellas in the right place. At that moment an idea came into his mind. He ran to his desk and drew pictures.
