Thunder Can't Hide under Trees Many times, when we walk in an open place, it suddenly rains. Without an umbrella, we will find a place to take shelter from the rain, and we will also take shelter under a big tree. Scientific experiments tell us that when it thunders, we can't take shelter from the rain under the tree, because lightning will first touch the tallest object on the ground, and then spread to the earth. People standing under the tree will also be struck by lightning, often losing their lives. According to this scientific principle, people install lightning rods for tall buildings. 本文来源：https://www.wddqw.com/doc/cd58cc490440be1e650e52ea551810a6f524c8f4.html
