Creating a plant-based cosmic ray observatory using outdoor plant boxes is an innovative and accessible way to explore high-energy physics at home. Here’s a step-by-step guide to help you get started:

1. Select the Right Plant Boxes: Choose sturdy, weather-resistant outdoor plant boxes. Ensure they have enough depth to house your detection setup while allowing plants to grow naturally.

2. Incorporate Detection Materials: Cosmic rays interact with certain materials, producing detectable signals. Line the bottom of the plant boxes with sheets of scintillator material or even simple photographic film, which can record particle impacts.

3. Integrate Plant Life: Plant fast-growing species like sunflowers or beans. Their height and foliage can help shield and stabilize your detection setup while adding a natural aesthetic.

4. Set Up Data Collection: Use low-cost sensors, such as Geiger counters or Raspberry Pi-based detectors, to monitor cosmic ray activity. Connect these to a small solar-powered data logger for continuous recording.

5. Analyze and Share Data: Regularly check your data for spikes in particle activity. Compare your findings with online cosmic ray databases or share them with citizen science projects like CRAYFIS.

This project blends gardening with cutting-edge science, making cosmic ray observation both educational and sustainable. Happy experimenting!
