@radcliff, that’s not how photons work.
An explosion is caused by a chemical reaction involving oxygen. This chemical reaction takes place at a much larger scale than photons even exist at. Also, photons themselves mediate (carry the force) of the chemical reaction. An explosion is, in a way, made of photons.
Your question is sort of like asking “how many taste buds does a cell have?” Cells don’t have taste buds. Taste buds are made out of cells.
