  • 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





  • I think there was a similar case, but about the mother. The courts took her baby and she was on trial for kidnapping.

    Eventually a geneticists saw it on the news and suggested she got tested again using DNA samples from other parts of her body and they found out she also was a chimera.

    Some racism was involved as she was working class and black, so the courts were just looking for a reason to take her baby and throw her ass in jail…
