I've seen this video about a million times and it never ceases to amaze me... yeah, it's all tricks, but you don't start REALLY dancing until you're older anyway.
I did a summer program a couple years ago and I danced with a girl who was ten years old. She had naturally perfect turnout and could do triple pirouettes on both sides EN POINTE. (I can rarely pull off a triple to the right en pointe and I'm almost seventeen!) And she was TOTALLY strong... ahhh, it was crazy.
