Sky Dancers

Kids like dolls and they like helicopters, so in the late 1990s, Galoob Toys Inc. combined the two ideas and created the Sky Dancers doll series. These dolls were set on a beautiful base and spun fast when a string was pulled. The Sky Dancers would zip up into the air and majestically soar directly into your father's face, blinding him, because their loose arms were in the shape of propeller blades.

This isn't a joke. Yes, the dolls could fly. However, they did so in an unpredictable manner, and, like grapefruit juice, it tended to shoot into the eyes of the unwary. The company got 170 instances of the dolls colliding with individuals, resulting in eye injuries such as damaged corneas and temporary blindness. Then there were the other injuries: stitched wounds, fractured teeth, a broken rib, and even a concussion. Thus, it is one of the Most Dangerous Kids Toys of All Time,

More product testing might have indicated that small plastic dolls flying erratically through the air inside a person's house were a bad idea.
