The proportions are way off, you're never going to reach Mars this way. You only need 1 mentos per 1 - 1.5 liter of coke
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?
technically mentos is the catalyst
That's the trick, it's actually about advertising to increase the total NASA budget so that they can actually get some space travel done
you need about 18000km/s delta V to go from Earth's surface to Mars's surface.
A mentos+coke gets about a couple meters per second delta V.
no, you cannot use 18 million bottles, because of the rocket equation
Not with that attitude, you can't!
"Equation esmation!"
