On a cold winter night, a little match-selling girl stands on a dark and lonely street. She is good at science and remembers what her teacher told her about the Periodic Table of Elements. She strikes a match head, heats up the red phosphorus, burns it with sulphur, and mixes with oxygen to make heat and light. She is very happy, as every match can keep her warm for a few seconds. The girl repeats the steps, wondering which element can make an everlasting heat and light, before burning out all the matches.
