Banana leaves to this day and still, have been used by people in many countries. Their large and flexible quality enables for a wide range of applications such as cooking. Some people use these to heat their food or to use as plates. Banana leaves are waterproof and help keep in heat for foods such as rice. Its waterproof quality should enable no need for a plastic lining to prevent leakage. When making a prototype by hand, the bamboo cup was able to hold both hot and cold water but for a limited amount of time. Though its flexibility allowed it to be bent into the shape of a cup, it also made it hard to hold. Attempting to find the best way to hold it gave way to a tear and even just one is enough to break it whole. This then gave the idea that perhaps the entire cup may not have to be made of banana leaves. The paper can still be there with the leaves as a lining to prevent leakage. This both works to help keep the shape of the cup and remove the need for plastic or wax linings. Even rolling up a piece into a straw allowed water to travel up. I was able to obtain a package of the banana leaves from a market for $2.50. Imagine how much cheaper and economically affordable it would be if it was a wholesale purchase.
