its real easy to split water (h2o) into it's componets, hydrogen and oxygen and then cause a huge flame when you ignite the hydrogen in the presence of oxygen and recombine them. i can do it on a smaller scale by putting copper wires into opposite ends of a potatoe and placing the wires into a saline solution. the real problem is storage and delivery, thats where entropy enters into the equation.
