Greetings and welcome to another edition of Science Sunday! Today we are talking about electricity- specifically about one of Nikola Tesla’s most notable inventions. Many of you have probably heard about the car company Tesla, but have you ever heard of the Tesla coil? We can use the Tesla coil to make electricity. Tesla coils are comprised of coils with capacitors, which can store a charge. The Tesla coil will continue storing charge until it becomes so full that it can jump through the air.
Here is something to note, when you think you are seeing electricity, you are not. Electricity is invisible. What you are seeing is the air molecules getting so hot that they are frying. Want to see us light up a fluorescent tube without using any wire? Click here.
There is a popular toy that many of you have either seen or played with yourself that uses the same Tesla coil inside. Any idea what it might be? Have you ever heard of a plasma ball? The plasma ball works in the same way. It is a Tesla coil inside a clear globe that might have argon or another noble gas inside of it. When you place a hand on that globe, the electricity appears to follow wherever your fingers go. This is because you are giving that electricity a quicker path to the group so it will be attracted to your fingers.
