Prototype

Here is my prototype which i made using jute and sun board, i think that the actual product
can also be made up of jute as it is a good insulator and is widely used in India to
preserve ice from melting. The pores present in jute enables the air to trap inside them which
restricts the entry of hot air so the thing
kept inside the jute  remains at its temperature i,e milk shakes
