Is a flame really a plasma? Well it depends on your definition of plasma, but there are certainly ions in a flame, formed as molecules collide with each other at high speed, sometimes knocking electrons off of their atoms.

Special thanks to the Palais de la Decouverte for helping me perform this experiment. Using tens of thousands of volts on two metal plates, we created a strong electric field around the plasma. This pulled positive ions in one direction and negative ions in the other direction elongating the flame horizontally and causing it to flicker like a "papillon" (butterfly). Then we showed that much longer sparks can be made through the flame than through air since the ions increase the conductivity.

What if you put two candles in between those plates. Can the spark jumps between the candles?

Isn't it interesting? Plasma was discovered as a state of matter pretty late compared to solid, liquid, gas, whereas the classic "four elements" mentioned at least 2.500 years ago, maybe even 5.000 years ago, include "fire"... and now we know "fire" (the visible flame) is plasma, meaning the four elements were indeed representations of these four states
