The authors describe why you would want to build a cosmic ray cloud chamber and provide a link to instructions.

The QuarkNet Cosmic Ray e-Lab supports hands-on research on cosmic rays. The Cosmic Ray e-Lab portal presents analysis tools, and the QuarkNet Cosmic Ray Muon Detector (CRMD) allows students to take actual measurements of cosmic rays. The constant flux of protons and muons particles from deep space prompts the asking of interesting research questions. While the quantification of data is critical to student research, frequently students lack tangible evidence of what they are measuring. "Can we see them?," students ask. Sometimes seeing is believing.
