Science | Science Experiment of the Week 12 | 324 - Tummy Rumbles

Stomach Growling, Noises, Intestines, Digestive System - This week's experiment came to me as I was thinking about food. I was trying to decide what to cook for supper when suddenly my belly made a rumbling growl. Instantly, I knew what I would do for this week's experiment.

This Week's Experiment - #324 Tummy Rumbles

These experiments are from Robert Krampf - The Happy Scientist

This week's experiment came to me as I was thinking about food. I was trying to decide what to cook for supper when suddenly my belly made a rumbling growl. Instantly, I knew what I would do for this week's experiment. You will need:

food that you really like

The first thing to do is to place your hand on your stomach. Go ahead, do it right now. Are you ready? Do you have your hand on your stomach? Are you sure? Unless you know your insides pretty well, you probably have your hand in the wrong spot. Most people put their hand on their belly, just above their navel. That is not where your stomach is.

To find your stomach, place your right hand over your heart. Ahh, got you again. Your heart is not on the left side of your chest. Actually, your heart is in the center. It is tilted, so you hear it more on the left side, but it is in the middle.

OK, back to finding your stomach. Place your hand on the left side of your chest, as most people do when they think they are putting their hand over their heart. Then move your hand down about 2 or 3 inches. Your little finger should be just about on the bottom of your rib cage. If you press in, you should feel ribs under your fingers. Your wrist should be just to the right of the center. Now, your hand is just about where your stomach is.

Well, if your stomach is up there, what is in your belly, where you put your hand the first time? It is your intestines. When your tummy rumbles and you say that your stomach is growling, it is probably your intestines instead.

To test that, wait until you are hungry. Then we will use your favorite food to get the rumbles started. If you are really hungry, just thinking about food will do it. If you are not quite that hungry, you may need to smell it or see it. Don't eat any yet. Wait until you hear and feel the rumbles. Where are they located? Some of the sound may be coming from your stomach, but most of it is probably coming from your intestines. Your body is preparing for the food. Your digestive system is becoming more active, with the muscles squishing things around more and more digestive juices flowing. That gets things sloshing around and gives you all sorts of interesting noises.

When you are through listening to your body, then you get to eat the food that caused the sounds. Who said science wasn't any fun?

Have a wonderful week.
