A rapid version prototype to help me think about how human can interact with an hourglass a like object. I made this hourglass out of simple plastic glass from Poundsland in order to help me see how sand works with the movement and to help me check what are the necessary parts that  need to concern. After I finished, one of my class mate , Stefanie , came to see and we have some discussion about the feasibility of it. She point out some useful technologies that could fit my object. She also draw me a diagram of how it should function.
