Worms wiggle. This can make it hard for fishermen to impale them on a hook. But in 1989, Loren Lukehart of Boise, Idaho offered a solution. He received a patent (No. 4,800,666) for a method of “dewiggling” earthworms.
His invention was essentially a rectangular box full of sand. From his patent:
Once the sand coated earthworm is immersed in water, the sand rinses free and the earthworm resume its normal wiggly character.
