Today we brainstormed two different thermos designs. We also
researched a bit and discovered some good heat insulators that could be used in
our thermos; such as wool and foam
For the first design we
thought of cutting the top of the bottle so that we could build our own that would act as a better insulator than the original. Afterwards additional insulators would be
added around the bottle; this would secure the thermos from heating being transferred out
of the bottle. However we realized that
cutting the bottle could be a risk because it would create a bigger surface
area for releasing heat.
Thus idea#2 was designed, which had a narrow top opening, and
instead of having a plastic-foam layer surrounding the bottle, tin foil, tape
and wool would be used. In the process of design#1 we had trouble thinking how
to support the thermometer from falling, but in design#2 we got some ideas from
the teacher which led to using an eyedropper. The eyedropper would be cut in the middle where the thermometer
would then be inserted, and the rubber part of the eyedropper would be sticking
outside of the bottle so it wouldn't fall.
