Transcript

This mask starts out soft, but turns rock hard while it's on your face. It's made from a special thermoplastic used in cancer radiotherapy. Doctors heat it, place it over the patient, and as it cools, it hardens into a perfect mold. Then, it's locked to the treatment table, because during radiation, even the smallest movement can ruin the treatment.
