Yo-yo

Have you read the research that your friends have done on yo-yos? Do you understand how they work?
The yo-yoist winds the string tightly around the axle. Sitting in the yo-yoist's palm, the yo-yo has a certain amount of potential energy. The yo-yo is held up in the air, giving it the potential to fall to the ground. The yo-yo has string wound around it, giving it the potential to spin as it unwinds.When the yo-yo reaches the end of the string, it can't fall any farther. But, because it has a good deal of angular momentum, it will keep spinning.

King and Queen of Yo-yo :)
Do also check out the websites that show the stunning moves by the yo-yoists. Some of your friends have sourced out really interesting websites

    Oh :) Your father and brother also know the tricks? Do you want to video them doing their tricks and share with us? How are you? Still feeling feverish?
