Learn Morse Code
You and your friends can learn to send secret messages to each other by using Morse code. It’s relatively easy to learn. Print off the chart below for your own Morse code list. You can use Morse code in many ways do this either by tapping on walls, clicking with spoons, or even using a flashlight at night. The circle represents a short tap or flash of light. The line represents a long tap or flash of light.
For example to spell S. O. S. – use three shorts, three long, and three shorts.
