This raises so many questions .....

This reminds me of why I got into chemical engineering. Had a guest speaker in high school that was a ChemE and used his experience as an expert witness. One of the cases was where a tire exploded when a service tech went to pull a nail out of the tire. Ended up being due to the fact the person who owned the tire had used Fix-a-Flat, but it did not have enough pressure to fill the tire pressure up fully. This guy being a typically handy fellow had an oxygen tank available and used that to pressure up the tire. This was not mentioned to the service tech and based on the calculations of the ChemE he determined that the heat from the friction of the nail being pulled out was enough to ignite the mixture in the tire.
