Mr. Williams takes us into Space with a simulated rocket

Mr. Williams at Sun Ed High has uploaded a guide to a simulation called KERBAL Space

You have a challenge.  Can you help the Kerbals (a species of human-like creatures) get into space?  Can you teach them to orbit their planet?

The video has a section about building a rocket starting around minute 5.  The rocket gets launched around 18 minutes into the video.   Mr. Williams has a theory:  perhaps the developers of the program want future space engineers to find out that they love engineering by using this simulation.

The cost of the simulation is around $40.
