Worm Grunting (read description)

"Worm grunting" is a technique used to lure earthworms to the surface for harvesting. It involves creating vibrations on the ground, typically by inserting a wooden stake and rubbing it with a wood object. The vibrations mimic the sound of rainfall, which prompts the worms to surface to avoid drowning. It's commonly used by fishermen and gardeners to gather bait or improve soil quality.
