So far you have the right answers, a mix of using oxygen, and a flammable gas, either natural or propane will work, the key is the mixture of the Lower explosive limits. In a flammable gas is is fro 8 to 12% of the upper explosive limits, anything within that range with explode, mixing 100% oxygen with the gas only makes the explosion more volatile, as shown in the video.I'm sticking with this scenario.
