2198. Odori-don. Odori-don is a sushi dish with a dead octopus that dances when soy sauce is poured on it. WHAT THE…

Oh, now this is interesting! To understand the science behind this curious phenomenon, think of the soy sauce - which has a high sodium content - as jolting the squid’s tentacles with tiny amounts of electricity. The energy in question lies within ions contained in the sauce’s aforementioned sodium content, which are used in cells to create voltage differences. As the squid is served fresh, the cells inside are still active and when the sodium is applied, the signals across the nerve cell membranes are temporarily reactivated causing the squid to “dance.”

this is terrifying
