We have all played with matches. There is something magical about them. They seem benign and harmless inside the box, but one strike and a single stick can burn down an entire building. Well, that's the case with fire, its either a handy servant or a dangerous master. 

So apart from helping us burn fuels, keep us warm, cook our food, fly our balloons and even our aircrafts, what can fire do for us. Well, our friend, The BackYard Scientist, shows in this video how you can create fires of different colours, just for pleasure.
