Problem Statement

This report outlines the design and prototyping process of the Science Museum Bernoulli’s Demo (SMBD), a capstone project for MEMS 4110 Senior Design Project at Washington University in St. Louis. The SMBD is a fun game for a children’s science museum designed to demonstrate how the exit velocity of water from a pipe changes based on the pipe diameter. The design intends to teach kids about Bernoulli’s principle by allowing them to choose from two different sized pipes to spray water at a target. The key aspect of the game is that the water flows more slowly out of the larger pipe, so they have to aim the two pipes differently to hit a target at a fixed distance. The initial prototype consisted of platform used to apply pressure to a container of water and then spray water out of two pipes. The f inal prototype stabilizes the platform, and constrains the container of water to a piston to increase pressure. The pipes were also downsized to allow for a higher exit velocity and a more entertaining demonstration. The Science Museum Bernoulli’s Demo is a great way to teach kids about the basic of Bernoulli’s principle.
