Welcome to Youth Radio, your radio.  Here we're proud to introduce three Amazing Kids.

Gina, who is thirteen years old, got first prize in the "Young Cook of the Year" competition and she wants to write a recipe book for kids. "I want it to be fun to read and easy enough for children to use," she says. Gina learned by watching her father, who's also good at cooking, in the kitchen.  She wants to encourage other children to cook because "everyone needs to eat so it's a skill that will always be useful!"

Seventeen-year-old Brian used to love running until he was hurt in a serious accident three years ago. He lost part of one leg and didn't even expect to walk again. Now he's an athlete who has recently taken part in a long race.  "After my accident I wanted to give up," he says. "But now I'm happy to be alive and able to continue running."

Helen has always been good at science, but she thought it was too difficult to become an inventor. Then she heard about an accident that had happened when a car hit a train in her town.  "That gave me an idea," says the clever sixteen-year-old. It took her over a year to invent a small special machine that tells car .drivers when a train is coming. One company is already interested in selling it, so it may be in he shops soon!

Do you know a child like them? Please e-mail us at amaxingkids@ mail. com and tell us why he or she should be on our radio. Thank you.
