• The building of the project took 5 hours of The building of the project took 5 hours of work by all five team members. This time was work by all five team members. This time was used to design, build, yell at, and break used to design, build, yell at, and break “Pinball Tubulator Mach III.”“Pinball Tubulator Mach III.”
