========== What is a candle flame really made of?I am at the Palace of Discovery in Paris to
do an experimentthat beautifully demonstrates the answers.Ok so we're turning on an electric field hereand we see that the flame is spreading out.Thats very cute,it's like a butterfly.And you can see that the flamehas two separate pieces to it now.One is going towards the negative plate.Those would be the positive ions,and the negative ions will be going
towards a positively charged plate.So we see the flame kinda flattening out.But if that didn't convince youthat flame contains ions,then check part two of our experimentwhere we compare the conductivity of aflame to the connectivity of air,which is normally a pretty good insulator.It requires about 10,000 vo...
