Are there some days when you don’t want to take a bath? An invention called DryBath

can solve your problem---you can get clean by using it without taking a bath!

A few years ago, Ludwick Marishane and his friend enjoyed a day at the beach. At the end of

the day Ludwick’s friend was so tired that he didn’t want to take a bath. Then an idea came into

Ludwick’s mind---why not invent something to help people get clean without taking a bath?

Ludwick ran home, did some research (on his mobile phone because he didn’t have a computer)

and over time invented DryBath.

During his research, Ludwick also learned that over 2 billion people in the world live

without improved sanitation (卫生设施). That’s about one third of the world’s population.

Ludwick wants to help not only his “lazy” friend, but also people who can’t easily get clean.

Staying clean can help people keep in good health.
