Could the prince really have scaled Rapunzel's hair to rescue her? In fact, he could have, although it would have been safer for him if she would have had darker hair and safer for her if she would have tied her hair around something before throwing it down. An average strand of hair can hold three and half ounces, an average blonde has 140, 000 strands of hair, so the prince and a couple of his friends could have climbed the tower. If Rapunzel didn't tie her hair around something first, though, her hair would have ripped right out of her head.
