You will need two clear plastic cups, water, a pencil, a piece of paper, and a flashlight.
Fill one cup with water and place it on top of the piece of paper. Place the other cup upside down on top of the first cup. Use the pencil to make a small hole in the bottom of the top cup. Shine the flashlight through the hole and you will see a small image appear on the paper.
It is best to use clear plastic cups, as they allow the light to pass through easily. You can experiment with different types of cups to see the effects on the image.
This project demonstrates the basic principles of how lenses work. It also shows how light can be refracted and manipulated to create images.
Yes, you can use this lens to magnify small objects by placing them in front of the hole in the top cup. You can also experiment with different distances between the object and the lens to see the effects on the image.
