It’s impressive how common, unassuming things around us work, and how little we often know about them. For example, flames that we often see are actually capable of conducting electricity. A flame is mostly composed of plasma where the ionized molecules and atoms can conduct electricity.
However, for a flame to be plasma, it should have a temperature above 1500 degrees Celsius. A candle flame that does not reach this temperature is generally considered to not be plasma. Yet, as the video above shows us, it is fairly capable of conducting electricity. In fact, watch the video to the end, and you will notice that once the flame goes out, the smoke behaves in an equally interesting manner.
