Re: [spam][ot][rambling][crazy] Building a Spaceship Out Of Something Ridiculously Weak and Flimsy

I read a few links from https://www.grc.nasa.gov/www/k-12/airplane/rockth.html and I get the impression that the thrust a rocket can produce is going to be a function of the number of gas molecules produced when combusting its fuel at its temperature of combustion. I'm guessing that would be determined by the density of oxidizer in the fuel mixture and the density of combustible carbon molecules in the fuel. So, we might be able to figure out how much tissue paper, toilet paper, leaves, or cardboard from a dumpster, we might need to make a rocket engine comparable to one built by nasa, by comparing the density of combustible carbon molecules in the comparable fuels and dividing by the ratio of density of mass.
