Lauren Rojas,a13-year-old girl,once watched a television programme. In the programme,a balloon was released into the sky. She thought she could do the same with her Hello Kitty doll.

Lauren spent about a month building a small silver rocket and a weather balloon by herself. She put the Hello Kitty doll into the rocket and tied it with the balloon. After testing wind direction and temperature, she set the balloon free. Lauren Rojas said she wanted to test the effects of altitude on the balloon's air pressure and temperature. To record the journey, she put cameras to the rocket.

After a few minutes,the balloon rose more than 90,000 feet above the ground. It was near outer space. There,the air was so thin that the balloon burst. The balloon was 53 times larger than its original size before bursting open. Hello Kitty's rocket fell back down to Earth with the help of a parachute. It landed in a tree 47.5 miles from the launch site.

Hello Kitty went along for the ride in the rocket just for fun. "I have liked her ever since I was 6 years old," Lauren told the New York Daily News. " I thought it would be really fun to add a toy inside the rocket. "
