With a mass of 2 million-trillion-trillion-trillion kilograms, it weighs as much as 330 000 Earths. This huge ball of superhot gas is 1.4 million kilometres across, equal to 109 Earths set side by side. Without the Sun there would be no daylight, and our planet would simply be a dark, frozen world, with no oceans of liquid water and no life. It also gives out dangerous ultraviolet light which causes sunburn and may cause cancer. Make predictions about what you think will happen, and then see if you guessed correctly.The Sun is our nearest star. Before conducting the experiment, read the instructions thoroughly. Up for a challenge? If you have access to both a plasma ball and a fluorescent light bulb, you can try the Plasma Ball and Fluorescent Light Experiment.Will it inspire them to learn more about plasma balls? If so, share what you've learned with them! What colors will you use? Share your work of art with a friend or family member. Aren't plasma balls super cool? Can you capture the beauty of a plasma ball in your own work of art? Get out your art supplies and create a picture or sculpture inspired by the colorful, electric plasma ball.Browse through the options and choose one that looks fun and exciting. Be sure to get help from an adult friend or family member. Jump online to check out Energy and Electricity Experiments. Curious to know more about electricity? There are a ton of fun experiments you can do right at home.Wasn't today's Wonder of the Day simply shocking? Check out the following activities with a friend or family member to learn even more: When you touch the glass, you create a discharge path with less resistance than the surrounding glass and gases. This phenomenon occurs because of the conductive properties of the human body. It's like creating your own personal bolt of lightning from the electrode to your finger! If you've ever touched a plasma ball when it's on, you know that placing your finger on the glass draws a colorful strand of light to your finger. Common gases include neon, argon, xenon, and krypton. The colors depend upon the gases used inside the plasma ball. This current flows through the plasma filaments to create colorful tendrils of light. The electrode at the center of a plasma ball emits a high-frequency, high- voltage alternating electric current. The modern plasma balls popular as novelty and educational items today were first designed by Bill Parker. That's why the electrode at the center of a plasma ball is also often known as a Tesla coil. The plasma ball was invented by Nikola Tesla when he was experimenting with high-frequency electric currents in a glass vacuum tube.
Plasma filaments extend from the electrode to the glass when electricity is supplied, creating fascinating beams of colored light. The Southwest Research Institute defines plasma as “a hot ionized gas containing roughly equal quantities of positively charged ions and negatively charged electrons." Plasma is considered a fourth state of matter that's different from solids, liquids, and gases.Ī plasma ball - also sometimes called a plasma globe, lamp, dome, or sphere - is a clear glass ball filled with a mixture of noble gases with a high- voltage electrode at its center. Although it sounds a bit mysterious, plasma is actually the most common form of matter in the universe! It's even more common than solids, liquids, and gases! So what exactly is a plasma ball? Before we can answer that, let's first take a look at what plasma is. If you've ever seen one of those clear glass balls that lights up with what looks like bolts of electricity that stretch from a central orb to the place where your fingers touch the outside of the glass, then you know how cool plasma balls really are!
This is especially true if you have access to a plasma ball! When you learn about electricity in school, though, it can be a fun and exciting time. Can you imagine what a struggle it would be if you couldn't plug in just about anywhere to recharge the devices you rely upon every day?Įlectricity is all around us every day, and we usually don't give much thought to it. Today, we take these items - and the electricity that runs them - for granted. Just kidding! Life was quite different back in the days before mobile phones and tablet computers. It must have been even harder for them to charge their devices without electricity!
When you study history, do you have an appreciation for how early humans survived way back when? Hunting and gathering food in the wild must have been a big challenge.
