Gravity Container & Physics

My 9 year old daughter Charlie wanted to create her first print and join the Physics Education Design Contest. The result is this funky container that we used to learn about gravity, velocity and angular velocity. While we kept to basic physics concepts since she is only in elementry school, there are many experiments/problems that you could run/solve and learn with this gravity fed container. Below are some experiments/problems that I think would be appropriate for middle school through college for some. When you are done experimenting, enjoy the container.
