Materials Justification

I am going to use vacuum forming plastic to create my design because it is the best way to make my three spheres. Although it may be rather difficult to make all the shapes fit together there isn’t a way it would be easier, and by having a flat bottom on the circles we can make it work. The plastic I will use to make it (Acrylic) is relatively cheap. The polystyrene for the mold is cheap too. It is an ‘economical process’ so we won’t be damaging the environment too much, which is important. Overall it is a versatile and easy to use method that will be the best way to make my design happen.
