I am speaking on behalf of one of the members of my team. WHY ARE WE USING TUBIES???
The game and kit team decided we wanted a new engineering challenge for the students. In the past we always used balls and some teams just recycled their designs and there was no real growth of the team.
Many factors are taken into consideration in the game design process and we spend many hours on the process.
Any adult is welcome to join us to have input. Sorry, students are not part of the group.
