What's that in the sky? Is it a bird? Is it a plane? No, it's Hello Kitty.
That's how Lauren Rojas, 12, from the US thought of her science project. She sent her Hello Kitty doll into the sky early this month. She wanted to find out how altitude(高度) changed air pressure(气压) and temperature, according to New York Daily News.
Rojas put the doll and a small computer into a rocket model, and then sent it up with a weather balloon(气球). The computer recorded the height, air pressure and temperature. Rojas also put in a video camera to record the trip.
"It took about two or three weeks to put it all together," said Rojas. "I think people will think it (the video) is really cool."
The balloon got to 28.5km above the Earth. At that height, the doll could see the blue curves(曲线) of our planet. The air was very thin up there, and soon the balloon broke up (爆炸). The doll fell from the sky and at last it ended up in a tree. It was 76km from the place where it had started its journey.
