Expectant fathers and mothers who want to know what the baby looks like in the uterus must rely on ultrasound. A postgraduate student of the Royal College of Art in Britain has made a model of the same size as the real fetus with the help of advanced technologies such as ultrasound. The model also "grows" as the fetus grows, so that it can really record the process of the growth of the baby and allow parents to witness the day-by-day growth of the baby.
