The biggest challenge faced by travelers especially those who like to have a hiking trip is how to ensure a steady supply of clean clothes. Now, thanks to a great invention called Scrubba Wash Pack, that worry may be a thing of the past.
The portable washing machine was invented by Ash Newland in 2010, while planning to climb Mt. Kilimanjaro. Struck by the limited packing space, he got inspiration from traditional washboards to create a bag that could be used to clean clothes. Then he gave up his career as a lawyer and focused on perfecting the bag’s design. By 2012, the bag was ready for the public. It weighed only 180 grams and required very little storage space, making it perfect for anyone wishing to travel light.
Not surprisingly, the bag worth 55 dollars was an instant hit with travelers, university students and even passengers. However, Newland was not satisfied. He still saw a disadvantage with his invention – dirty clothes had to be carried around in a separate bag! The recently introduced Scrubba Wash Pack solves that problem.
In order to make the pack active, dirty clothes are placed inside the bag along with two to three liters of water. The bag is then shut tightly to ensure all air is squeezed out and the clothes are massaged (揉搓) for a few minutes. After a quick wash, they are clean and ready to be dried. According to Newland, the pack can clean anything from jeans to smelly socks! What’s even
more amazing is that with a capacity to hold 13 liters of water, it can be used to wash more clothes at a time.
The best part is that the 99-dollar pack that will be available for sale later this year, only weighs 300 grams and is completely foldable, making it easy to store when it’s not in use. With the Scrubba Wash Pack, wandering through foreign cities searching for a washing shop, or paying for washing machines may soon be a thing of the past!
1.What aroused Ash Newland’s desire to create the Scrubba Wash Bag?
A.Travelers’ requirements. B.His own experience.
C.His dream of invention. D.A traditional washboard.
2.Why wasn’t Ash Newland satisfied with his former invention?
A.The bag was not convenient enough.
B.The bag was not popular with travelers.
C.The bag couldn’t wash more clothes at a time.
D.The bag couldn’t be folded up.
3.Which word can best replace the underlined word in paragraph4?
A.Blown. B.Pushed
C.Figured. D.Run.
4.It can be inferred that the improved Wash Pack ______.
A.will lighten the burden on housewives
B.will replace the traditional washing machines
C.will be widely used by more travelers in the future
D.can encourage more people to travel a long distance
