Here is a great way to blow huge flames more than 10 feet high without using any toxic chemicals. This method uses food as fuel. It is much safer than alcohol or other fuels, not only because it is non-toxic, but also because the fuel is not really flammable until you blow it. It won't burn if you spill it on yourself. With that said, you should still be careful when playing with fire. I take no responsibility for any damage or injury you might suffer.
