Secondly, the initial evacuation, the airflow was strong enough to lift a penny against gravity, but there is no observable force on the scale.

What type of scale were you using? How many decimal places of pounds or Kg did it display? The scale would absolutely show the removal of the weight of the penny and some reduction in air volume were it accurate enough.


Additionally, you also said a nozzle is not required for a rocket to work in a vacuum in your previous post. So what you are saying is irrelevant. Optimization only occurs when the initial theory is proven.
 Quoting: Balance242


I had no previous post. You mistook me for someone else. The nozzle is absolutely vital in the acceleration of the rocket.

I’m sensing here that you know these things already and are just trolling though.
 Quoting: MaxTork


So you are saying that in order for rockets to work in space, they need to be equipped with the de Laval nozzle, otherwise rockets not equipped with this nozzle will not work in space?
