Creating a plant-based gravitational wave detector using outdoor plant boxes is an unconventional yet fascinating DIY science project. While traditional detectors like LIGO use lasers and mirrors, this experimental approach leverages the subtle movements of plants to detect cosmic ripples. Here’s how you can try it:

1. Materials Needed:

- Sturdy outdoor plant boxes (wooden or plastic)

- Fast-growing plants (e.g., beans or sunflowers)

- High-precision motion sensors (optional)

- Data logging software (for advanced setups)

2. Setup:

- Arrange the plant boxes in a stable, vibration-free outdoor area.

- Plant seeds evenly and ensure consistent growth conditions.

3. Theory:

- Gravitational waves may cause minute disturbances in plant growth patterns.

- Monitor plant movements or growth rates over time for anomalies.

4. Data Collection:

- Use time-lapse photography or sensors to track plant behavior.

- Compare data with known gravitational wave events (e.g., from LIGO alerts).

While this method lacks the precision of professional detectors, it’s a creative way to engage with astrophysics and explore the potential of bio-based sensing. Happy experimenting!
