divya jain great idea. I like that you also started prototyping. Have you also tested it with users to see how they perceive using your cup. Did you also test it with liquids. You might also check Mingjun Gao and team idea https://challenges.openideo.com/challenge/next-gen-cup-challenge/ideas/sustainable-cup-clay-cup-starch-coating Good luck with the development of your idea!

Hi Mingjun Gao Check also this other idea https://challenges.openideo.com/challenge/next-gen-cup-challenge/ideas/undo-the-wrong-switch-to-classy-earthenware
Ideation likes collaboration! Divya has also created some prototypes.

Hi Mingjun Gao and Sustainable Cup: Clay Cup & Starch Coating nice to see you experimenting with different materials. I wonder if you could also provide some connections to your research (e.g. existing use of clay for cups in countries like India). It might also provide some evidence on how this will be able to have liquids in them. You might also want to provide a story board to describe the different options. Just to confirm if you were to use clay, cups will be recycled after each use. Looking forward to seeing what you learnt from your first prototypes.
