The Olympic flame is always lit when the Olympics is on.
The flame is pretty because it is heavy, hot and bright and has lots of lovely petals. It is made out of metal (Copper) and sound like humming noises and like the wind.
The torch is seen at the Olympic Stadium and on the television. When the flame is lit it starts and when the torch is off it means it is finished.
The Olympic Torch is special to bring the counties together like a team. To make the Torch extra special each country gets to take home one of the petals of the torch at the end of the Olympics.
I think we are lucky that every country knows that the Olympic starts when the torch is lit.
