I WONDER - How Strong Is Hair?

Human hair is incredibly strong, with each strand capable of supporting up to 100 grams. With an average of 100,000 strands on a human head, the collective strength can support the weight of two elephants or three hippos. Additionally, when stretched, hair's strength is comparable to that of steel.

What is the significance of the number 100 grams in the context of hair strength?

What animals are mentioned in relation to the weight supported by hair?
