Extendable Cup/Bottle Prototype

This is a cardboard prototype of an extendabale cup. It is made fully out of cardboard, tape and a little bit of plastic

The cup can be extended from Small, Medium to Large. [Smallest on the right, Largest on the left]

This is a short demonstration of the cup. [20s]

This prototype was actually made for a class project. The prototype is suppose to represent a reusable cup for bubble tea shops in order to stop climate change by reducing the use of plastic cups. The cup can also be used as a typical water bottle and not just for bubble tea. The cup is extendable as bubble tea are sold at different sizes (small, medium, large). The prototype is 1.5x of the actual bottel size so that people can see it better for demonstration purposes. This cup although made of cardboard, is waterproof to better demostrate the purpose. The prototype if fully fuctional and can be used to hold water.
