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
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
https://en.wikipedia.org/wiki/Project_Orion_(nuclear_propulsion)
The whole unit was built into a can with a diameter no larger than 6 inches (150 mm) and weighed just over 300 pounds (140 kg) so it could be handled by machinery scaled up from a soft-drink vending machine; Coca-Cola was consulted on the design.[40]Whoa whoa whoa…everybody knows it’s diet coke that works best with mentos.
Apparently spacex doesn’t
I mean. Have you seen their owner lately? Also Trump needs all the diet coke for himself. You think we have enough to go around after he’s done?
Cybertruximus Promdate has no need for knowledge
Any r/theydidthemath refugees around to calculate the amount of thrust you would receive from something like this?
the questions are the specific impulse of those engines, then Delta-V.
a mentos and coke can reach about 3m height gayser, therefore initial nozzle velocity is 7.67m/s, and a 2l bottle lasts about 2 seconds. resulting in a ISP of 0.7822 seconds.
for comparison, the shuttle solid rocket booster has an isp of 250 seconds, a normal liquid rocket engine is about 450 seconds (the more the better).
plugging in the weights of the Saturn 1, gives a delta V of [drumroll] 18.6 m/s… enough to accelerate a giant rocket to highway speeds.
can we make it bigger to get to orbit? nope, the rocket equation won’t let you with that specific implied. sorry
Also, there would be ants everywhere in the vicinity after
that’s a plus, they’re cute
Fine, be that way. Maybe we can use it for the little psshhh pshh boosters they use in space on the spacesuits, etc. Don’t want to get too technical on you.
ok. but you can only maneuver 3 times before we run out of coke
Finally! Faster than light travel has been achieved!
