How to Use a Kaleidoscope

Invented in 1816 by Sir David Brewster of Scotland, the Greek word kaleidoscope means "beautiful form to see." Sir Brewster found he could create symmetrical patterns when he reflected small pieces of glass and other materials in mirrors or lenses. The endless symmetrical patterns you will find in kaleidoscopes will make it difficult to pass one by without looking through it.

Difficulty: Easy

Instructions

Things You'll Need:

• Kaleidoscope

1. Pick up the kaleidoscope and point it toward a light.

2. Grasp the kaleidoscope body with one hand. With the other hand on the top of the kaleidoscope, turn the top section while looking through the kaleidoscope lens. Continue to rotate the top of the kaleidoscope as you peer through it. You can turn it slowly or quickly to see the patterns.

3. Watch the colors and patterns as you turn the kaleidoscope. Pick several light sources, such as lamps with various degrees of light and sunlight, to view the kaleidoscope with. The patterns look different depending on the light you view it through.

4. Experiment with several types of kaleidoscopes. You can purchase them for a few pennies to thousands of dollars. Toy with reflective symmetry as you look into this wonderful creation.
