experiment for kids that shows how air pressure can be used in surprising ways. | | | | What you'll need: * Stiff plastic drinking straws * A raw potato Instructions: 1. Hold a plastic drinking straw by it sides (without covering the hole at the top) and try quickly stabbing the potato, what happens? 2. Repeat the experiment with a new straw but this time place your thumb over the top, covering the hole. What's happening?Placing your thumb over the hole at the top of the straw improves your ability to pierce the potato skin and push the straw deep into the potato. The first time you tried the experiment you may have only pierced the potato a small amount, so why are you more successful on the second attempt?Covering the top of the straw with your thumb traps the air inside, forcing it to compress as you stab the straw through the potato skin. This makes the straw strong enough to pierce the potato, unlike the first attempt where the air is pushed out of the straw. | Use a Balloon to Amplify SoundSmall sounds can still make a big noise when you use a good sound conductor. Experiment with a balloon, compressed air and your own ears to find out how it works and the science behind it. | | | | What you'll need: * Balloon Instructions: 1. Blow up the balloon. 2. Hold the balloon close to your ear while you tap lightly on the other side. What's happening?Despite you only tapping lightly on the balloon your ears can hear the noise loudly.…
