CosmicWatch is an outreach program that is being designed to provide students the ability to build their own in-expensive muon detector. A single detector costs approximately 100$. Each detector takes a novice high-school student approximately 4-hours to build for the first time and a second detector can be built in about an hour. 

Deteails and supplementary marerials are available in the GitHub repository:
