Watching soil does not seem like it would be an interesting thing to do, but Josh Williams has made it a hobby for himself and others with the use of a soil camera.
The blogger uses a waterproof scanner that he controls with 'Raspberry Pi' to look at what movements and processes look like under soil. After burying the camera for a determined amount of time, the artist reveals interesting footage of what goes on underground. Everything from roots growing in the soil to plants decomposing to worms and centipedes moving around looks surprisingly fascinating, especially with the quick pace of the videos.
These underground soil camera videos show a hidden world that most people do not often see and provide insights into how plants grow and the decomposition process.
