 Now, here's one way to use this strip of foam and sticks. There will be more later. Ever had someone look at the moon in your scope and say, hey, it looks upside down? Here's a simple way to explain why. Hand your visitor a spoon. When you look in the bowl of a spoon, what do you see? You see yourself upside down. Why is your image upside down? The spoon's surface is curved. Just like this telescope has a curved mirror in it. Let's pretend this is a mirror. When you look in a flat mirror, the light comes straight back out at you. Here's your chin and here's your forehead. But a spoon is curved. Now, where's your forehead and where's your chin? The same thing's happening in the telescope's curved mirror. If it's still daylight and you have a reflector telescope, ask your visitor to stand about five to eight feet in front of the telescope and look down the barrel. They may have to look off-center. They will see their image upside down. The image is also reversed, right for left. On the back of the spoon, some people will notice their image right side up, but it's elongated. What's happening to the light? Okay? The easiest way to manipulate the foam is to hold it like this at either end. You can then use your fingers to position the sticks if you need to.
