How to make fireballs that you can hold in your hands. Be careful though, it's still fire and can still burn you. Found this vid and thought it was cool.
WARNING
DO NOT USE LIGHTER FLUID. USE LIGHTER FUEL.
There is a big difference. Lighter fuel, such as the Ronsonol brand shown here, is a Butane and will light in the manner shown here. Lighter Fluid is Aliphatic Petroleum Solvent, and WILL burn you.
The dark blue area at the bottom of the fireball has a low oxygen concentration so the heat will be low, and you will be able to hold it in your hand, it will just feel warm. The upper part of the fireball however is HOT and can burn you, so you must be careful.
Again, be careful doing this and remember to use a Butane based Lighter FUEL used to refill lighters, NOT Lighter FLUID which is used to light charcoal.
