ISS microgravity water forms sticky blobs—risking suffocation & short circuits 🚀💧

Ajouté : 2026-05-16

In microgravity environments like the International Space Station, water forms cohesive blobs up to 10cm in diameter due to surface tension (72 mN/m) without gravity to break them apart, as demonstrated by astronaut Chris Hadfield; this creates significant risks including suffocation if water covers the face and short circuits in electronics, necessitating strict hygiene protocols with no-rinse soap and limited water usage.
