Throughout this experience I was proud of my self about the fact that I was able to make my own design and make it in to real life I always tried making little things such as hot air ballon and other things but I never got to actually make it work and be able to be used in real life. If I had a another chance that I can fix my prototype then I would make the handle part where we put the magnets to hold the pieces, we are going make hat part little bit more thinner to make the handle be more comfortable and easily handled. The hardest thing that I went over was when I used the magnets to stick the sides to getter but the magnet was not strong enough to make it not fall. Then we ended up adding a lot more of things on the cup insulator. The new skill that I learned throughout this project is that I learned to make reusable cup insulator to keep the thermal energy inside the cup. Even though I didn’t have a chance to test to out but the quality of this cup insulator in very good for preventing the heat loss of the hot water/ Coffee in the mug cup.
