Becoming an inventor may seem impossible, but it's not. Many inventors got their start when they saw a problem and tried to solve it.
Once they have an idea about how to solve a problem, budding (崭露头角的) inventors often talk to their parents, friends or teachers about it. "I often advise kids not to be afraid to ask someone for help," says Hart Main. He didn't know how to make candles, so he talked to someone who did.
As a next step, inventors often build a model of their invention. They might show it at a school science fair. A trip to a larger gathering, such as a Maker Faire, might follow. Maker Faires are like big show-and-tells for all ages, where inventors share their ideas and creations.
Students in grades five to eight can go to yearly competitions such as "America's Top Young Scientist". The grand prize is 25,000. Peyton Robertson, eleven, won this prize for an improved sandbag. Sandbags can protect places from flooding, but carrying heavy sandbags and putting enough into place can be hard and take a lot of time. Peyton's invention is lighter than a common sandbag. It gets bigger when it absorbs (吸收) water and protects better against flooding.
▲With their inventions, kids solve everyday problems and make people's lives better and easier. Maybe you will be the next great inventor.

A. don't waste time, or you will get nothing
