Three kids have been learning chemistry for only a few months. But they have already begun to challenge (挑战) a world famous scientist!Li Weichi, Huang Runling, and Xiao Yan are from Zhongshan Huaqiao Middle School in Guangdong. They have just found a red cabbage that could be a new kind of acid-base indicator (酸碱指示剂). They want it to take the place of litmus (石蕊) paper.
"We've learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other."
British scientist Robert Boyle discovered the use of litmus paper over 300 years ago. Now it is used widely in experiments all over the world.
But when the kids did some experiments in class last winter, they saw that the litmus paper didn’t turn very blue with base matter. It's hard to get a clear result.
Will there be a better indicator than litmus paper? The three kids decided to try and find out!
How? They went to collect over 40 plants in parks, gardens and markets. Then they ground (研磨) leaves, flowers and stems (茎) to get the pigments (色素) from them.
The kids mixed pigments with acid and base. They spent months watching carefully to see which paper showed the best colour change. They decided it was the litmus paper!
"It's our first scientific journey, Huang said, "But it makes me want to try harder."

Are you still doing the V for victory sign? It’s out. The latest popular hand gesture（手势）is to curl both of your hands and put them together to make a heart—shape. Known as “hand heart”, many young stars in the US including Justin Bieber , Blake Lively and Taylor Swift have done the move in recent photos.
“The heart — hand gesture means something between ‘I love you’ and ‘thank you’, ”said the country singer Taylor Swift,21.”It’s a sweet, simple message which you can send without saying a word.”
Taylor Swift often puts her hands above her head in the heart shape at her concerts. And she is believed to be the first to make the gesture popular.
Last month during a charity show, Justin Bieber and his superstar friends did it to help out three kids whose parents were killed in a car accident. The gesture became a real hit after that.
“It used to take longer for nonverbal（不用语言的）culture to move. But now ,with smart phones and the Internet, it’s much faster,” said Patti Wood, an American language expert.
In the Republic of Korea, the hand heart has been popular for a long time, in a different way. People there like making a “bigger heart” by putting their hands above their heads and making a heart shape with their arms. It means: “I love you.”
