👉 The laughing fluid, also known as churumi, is a unique, non-toxic, and viscous liquid found in the mines of Lake Chur in the Andes Mountains of South America. It is produced by the fermentation of plant matter, primarily the roots and tubers of the psychotria viridis plant, combined with bacteria from the genus Streptomyces. This mixture creates a viscous, yellowish-brown liquid that can cause intense laughter in humans, often described as an uncontrollable, joyful giggle. The exact mechanism behind this phenomenon is not fully understood, but it's believed to involve the interaction of certain compounds in the fluid with neurotransmitters in the brain, particularly serotonin and dopamine, leading to a release of endorphins and other feel-good chemicals. This makes laughing fluid a fascinating subject in the study of neurochemistry and the biology of laughter.
