Do I have to
Why can’t I just use pressurized air?
Let’s go to the simulator and try!
Add air (increase the air pressure) to the
pop bottle and Launch to see the thrust produced.
Most pumps (such as a bicycle pump) read out pressurized air
in pounds per square inch (lb/in2, or PSI). In
science the metric system is preferred, where pressure is
measured in Newtons per square meter (N/m2) also
known as "Pascals" (Pa).
How do you convert from PSI
to Pascals? Learn
