A message from the author of today s story: Do you ever wonder as you are reading a story, or hearing one, such as on a podcast, for example, what or whom has inspired a particular story? Picture this: imaginary directions or instructions for a story that the author creates after the story has been written or told. Imagine that these directives led to this story which in actuality they did not well at least the author had no idea of any directives of any sort when the story came into being.

The next time a car, plane, or train passes by, pay attention to the way that the sound changes as it approaches and as it is heading away. You should find that once it passes you, its sound is much different. Why? To find out, you will need: your ears a plane, train or automobile passing near you a sink or bathtub with enough water to cover the bottom Why does the sound change? The plane, car, or train is not changing its sound. The difference is that it is now moving away from you instead of towards you. To understand what is happening, put enough water into a sink or bathtub to cover the bottom. Tap your finger into the water and notice the ripples that spread out from it. Basically, the same thing happens when something makes a sound. The sound waves spread in all directions, just as the ripples in the water do. Now, stick your finger into the water and then move it slowly across the surface. Look closely at the ripples. Are they the same in all directions? No. The ripples in front of your finger are closer together, and the ones behind it are farther apart. Again, this is much like the sound waves coming from a moving object. The sound waves in front of a fast moving object are closer together. The closer together the sound waves are, the higher the pitch of the sound. When the plane passes, the sound waves behind it are farther apart and the pitch of the sound is lower. This change in pitch from a moving object is called the Doppler Effect. If you don't have a place nearby where you can listen to planes, cars, or trains, then ask any child to imitate the sound of an airplane flying overhead. Listen to the sound and you will hear them lower the pitch to simulate the plane going over. ]]> Thu, 06 Dec 2007 12:51:42 -0500 Doppler Effect 7276264 http://www.mefeedia.com/entry/emergency-eyeglasses/7276264/

If you wear glasses, then you know how challenging it can be to find your glasses if you have laid them down and can't remember where you put them. You need your glasses to find your glasses. This is a way that you can make a quick, emergency pair of glasses for yourself or someone else that needs them. You will need: someone that needs glasses a piece of stiff paper or aluminum foil a needle, pin, or sharp nail If you wear glasses, take them off. Look around you. Things probably look very blurry. If you don't wear glasses, ask a friend that does wear glasses to let you borrow them for a minute. By putting on their glasses, you can blur your vision. Now we are going to make some paper glasses. Put your glasses back on if you need them to see up close. Use the pin to make a small, round hole in the piece of paper. Hold the paper up to your eye and look through the hole. If you normally wear glasses, you may be in for a surprise. Things look almost as clear as they do with your glasses. They will look dimmer, but very sharp and clear. If you are wearing your friend s glasses, you should see a clear image, even through their lenses. To understand how the pinhole works, you will need to make another pinhole, very close to the original. Now as you look through, you will see a double image of everything. Add five more pinholes and the image begins to blur as you get more and more images overlapping. If you add enough pinholes, things will look the same as they do without the pinholes. Think of looking at things without your glasses as looking through a tremendous number of pinholes all side by side. Using a single pinhole lets only a single image through, so it is dim, but in focus. In an emergency, you can even do without the paper. Put the first finger and thumb of your right hand together, as if you were pinching something. Do the same with your left hand and then bring your hands together to form a small opening between your fingers and thumbs. Look through this tiny hole and it will work just as your pinhole did. I have even seen adds in novelty catalogs for emergency glasses which were actually just cardboard glasses with cardboard lenses. Each lens had several pinholes in it. A neat idea, but not at $19.95. ]]> Wed, 28 Nov 2007 09:36:52 -0500 Emergency Eyeglasses 4755977 http://www.mefeedia.com/entry/hear-the-ocean/4755977/

Can you really hear the ocean in a seashell?

When I was a kid, I heard that if you held a sea shell up to your ear, you could hear the sound of the ocean. At that time, I had never been to the ocean, but the distant roaring sound from the shell sounded like an ocean does on TV. Now I live at the beach, and listening to a sea shell still sounds like the ocean, but is it. You can do an experiment to find out, and you don't even need a sea shell. Instead, you will need: a drinking glass Hold the opening of the glass against your ear, as if you were listening to something that was inside the glass. What do you hear? Sort of a static/roar sound. Wait a minute. Supposedly, the shells come from the ocean and that is why you can still hear it inside. That glass probably did not come from the ocean. Maybe you are hearing the sound of the dishwasher? To find out about the sound, you want everything to be VERY quiet. Wait for a time when nothing is going on. Turn off the TV. Go ahead. Turn it off. Nothing horrible will happen. Once you have the room very quiet, listen to the glass again. The ocean sound is very dim, and if you have things quiet enough, it may be gone. Now, you want some noise. Turn the TV back on. (See, I told you it would be OK.) Turn on some other noisy things. Once the place is good and loud, listen to the glass again. Now the ocean roar is very loud. What is going on? Our experiment gives us the information we need. The sound you are hearing is related to the sound in the room you are in. As the sound waves hit the glass, it vibrates. This causes the air inside the glass to vibrate, which causes the "ocean" sound. The louder the room, the louder the sound in the glass. Try listening to different things. Does a glass make a different sound from a shoe? What do you say when you hear the sound of a shoe? Geshunteit, of course. ]]> Wed, 21 Nov 2007 17:28:12 -0500 Hear The Ocean 3245277 http://www.mefeedia.com/entry/3245277/
