    This made me wonder, what is the fuel and oxidizer in a coke/mentos reaction?

    To me, it seems like coke is the fuel, and mentos is the oxidizer.

    Or would you say that coke is a monopropellant and the mentos is just the igniter?

      The fuel is CO2 gas within the coke that gets rapidly released by the surface texture of the mentos.

      Since the mentos doesn’t interact chemically it’s not an oxidizer, it interacts mechanically though so it acts as a turbopump maybe?
