Yes, the wire is what makes her legs bend.
I believe the legs on Barbie dolls with bendable legs are made of a silicone polymer, though I can't seem to confirm that right now. The ones with hard plastic legs are made of vinyl, which does not contain silicon.
No, Ballerina Barbie does not have bendable appendages. Her arms come pre-bent into ballet positions.
I think you are asking about one of the My First Barbie ballerina dolls.
The First Barbie doll could only move her legs up but couldnt bend them.. same with the arms
Flash Legs was created in 1977.
The earliest Barbie horse was Dancer, sold in 1971. She was chestnut brown, hard articulated legs and came with a stand.
Not all tables have metal legs, but metal is a strong cheap and light substance which can withstand compression well, making it ideal for table legs.
metal legs is translated 'jambes de métal' in French.
There is no American Girl Barbie. Or are you asking about the 1965 bend leg Barbie, who is often referred to as American Girl? I don't know about her arms, but her legs are similar to the 1971 Malibu Barbie's, and some collectors have bleached the Malibu Barbie legs to put on the bend leg doll.
The first Barbie doll to feature bendable legs was the American Girl model in 1965. Mattel, Inc. launched the Barbie doll in March of 1959. Barbie has since become a cultural icon, and Mattel has released dolls of different sexes, ethnicities, occupations, ages, and disabilities.

The Number 1 Barbie doll, which had a tube running through her straight legs so that her feet could be placed over a stand, was sold in early 1959. The Number 2 Barbie doll, which had the tube removed, followed in late 1959.
