This reminds me of when you see how some tire mechanics bead large truck tires. You can't just inflate them with air naturally. This is because the tire is commonly squashed down during transport and is then too narrow to reach the bead edge of the rim it's being mounted on. So, to get the tire to bead, an explosion is required. Usually, engine starter fluid is used in these cases. But you can't just spray in starter fluid, set it on fire and the tire just magically pops right on. Sure, the fluid will burn. But you need to balance the amount of air to fuel correctly to achieve the explosion. This is called a stoichiometric ratio. This formula also applies to all types of combustion engines. I had to learn all about that in emissions testing class.
