The UW Mobile Planetarium Project is a student driven effort to bring astronomy to high schools and the Seattle community. We designed and built an optics solution to project WorldWide Telescope in an inflatable planetarium from a laptop and off-the-shelf HD projector. In our first six months of operation, undergraduates at the UW gave planetarium shows to over 1500 people and 150 high school students created and presented their own astronomy projects in our dome, at their school. This document aims to share the technical aspects behind the project in order for others to replicate or adapt our model to their needs. This UW Mobile Planetarium was made possible thanks to a Hubble Space Telescope Education/Public Outreach Grant.
