(Demonstrate how a magnet destroys the validity of a compass by causing the needle to veer from North)
Scouts, you have learned to rely on your compass. You know that the needle points North and will guide you in the wilderness, but you have also seen what happens when a magnet is brought near the compass. The magnet is an outside influence on the character of the compass.
Each Scout has an aim in life. He wants to grow up to be physically strong, mentally awake, and morally straight.
The points of the Scout Law make up the magnetic field that directs the compass needle we follow.
Just like the magnet, there are influences trying to change our aim. There are temptations difficult to overcome - temptations to get by without working, to lie, to cheat, to follow the coaxing of friends, and the jeers or threats of enemies.
If you are going to grow up to be physically strong, mentally awake, and morally straight, you must not succumb to the attraction of the evil magnets in your life but must be steadfast in your purpose of living up to the ideals of Scouting.
