The project is about trying to explore and invent something out of my prior knowledge and hopefully helping other people. The materials are plastic containers, a plastic lid, rubber tube, water bag, heat pack, aluminum foil, 2 AA batteries, battery holder, wires (not powered), 3 prong toggle off and on switch, a light bulb and a fork. I got inspired by those instant soup bases for hotpot that use heat packs as their single exothermic heating agent, but they only stayed hot for 30-45 minutes. So I tried to add some modifications to the design and make it compact and minimalistic, along with making it prolong the period of time where it stayed hot. It took 2 months to design, tweak, and create the final prototype. I got help from Ms Laura when she supervised my project and she gave me feedback to make my presentation better and better. It stayed hot for over 2 hours after the presentation ended. I hope that in the future, I can mass-produce these lunchboxes and hopefully sell them so people can get a product that can help them during a natural disaster situation, (also good as a general microwave/heater).
