Bicycles are a great way to get around. They’re fun to ride, especially down hills. And, as you speed along the road, you might also think of ways in which you could improve your bike— make it safer, more efficient, or more comfortable. In fact, the two-wheeled machines make for some cool science projects.

This year's Intel International Science and Engineering Fair (ISEF), held last May in Cleveland, featured（had）three bicycle projects from three countries. Like many of the other experiments presented at ISEF, the bike projects showed that some of the most interesting scientific research often begins by taking a closer look at things you care about.

       Renato Angulo Chu had even grander ambitions. The 12th-grader from Lima, Peru, wanted to address some of his country's economic troubles.

"I see a problem in my country," Renato said. "If you go to the forests in Peru, in some places you cannot find electricity. If you go with my bicycle, you can turn on the lights."

Renato, 16, spent 3 years designing his special Multibike. The device looks like a fixed exercise bike. It has wires fixed along the frame and a blender strapped(fastened) to the back. Turning the pedals operates the blender. The same principle can be used to sharpen knives or sweep city streets.

       The Multibike can work either as a fixed bike or as a bicycle able to travel city streets and country roads. It's made from inexpensive materials, and the user gets exercise while pedaling to operate a machine.

"You pedal the bike, and you can mix any drink you want," Renato said. More importantly, he added, the same concept could be used to bring light to houses in remote regions of the rainforest.

In our life, we have rarely expressed our gratitude to the one who’d lived those years with us.In fact, we don’t have to wait for anniversaries to thank the ones close to us—the ones so easily overlooked. If I have learned anything about giving thanks, it is this: give it now！While your feeling of appreciation is alive and sincere, act on it. Saying thanks is such an easy way to add to the world’s happiness.
Saying thanks not only brightens someone else’s world, but it also brightens yours. If you’re feeling left out, unloved or unappreciated, try reaching out to others. It may be just the medicine you need.
Of course, there are times when you can’t express gratitude immediately. In that case don’t let embarrassment sink you into silence—speak up the first time you have the chance.
Once a young minister, Mark Brian, was sent to a remote parish of Kwakiutl Indians in British Columbia. He had been told that the Indians did not have a word for thank you. But Brian soon found that these people had exceptional generosity. Instead of saying thanks, it is their custom to return every favor with a favor of their own, and every kindness with an equal or superior kindness. They do their thanks.
I wonder if we had no words in our vocabulary for thank you, would we do a better job of communicating our gratitude? Would we be more responsive, more sensitive and more caring?
Thankfulness sets in motion a chain of reaction that transforms people all around us—including ourselves, for no one ever misunderstands the melody of a grateful heart.
