Video shows how silkworms make silk
According to a two-minute video, silk is produced by the larvae of silkworms which feast on mulberry leaves for about 42 days. They spin their silk cocoons for 3-8 days which are then loosened in hot water, unwound and spun into a thread. The video claims that it takes about 2,500 silkworms to make about half a kilogram of silk.\n
