As is know to us all, paper burns easy. Yesterday, Mike, a six-year-old boy, made a paper box and then filled it for water. He then lit a candle and tries to burn the paper box. Much to his surprises, the paper box didn’t catch fire. Such curious was the child about the experiment that he asked his father endless questions about it. His father, which is a teacher in a primary school, didn’t know how to ask these questions, but he didn’t pretend to understand. He did everything he could help his son solve the problem. This experience made Mike interesting in the study of modern science.
