adorable on Instagram: "The post's video shows gallium poured on an aluminum can, triggering rapid liquid metal embrittlement that forms visible white whiskers and causes structural collapse in seconds, a common demo mislabeled as mercury for dramatic effect. Mercury is banned on airplanes by FAA and EASA rules because it forms an amalgam with aluminum, dissolving the protective oxide layer and leading to hidden corrosion that weakens airframes, with even 1 gram potentially requiring costly part

Journey into the World of Physics on Instagram: "🚫 THIS IS WHY MERCURY IS NOT ALLOWED IN AIRPLANES ✈️ Liquid, shiny, and fascinating—mercury looks harmless at first glance. But inside an airplane, this tiny metal can quietly turn into a serious threat. Aviation safety isn’t just about engines and wings… sometimes, it’s about chemistry. When mercury touches aluminum (the primary material used in aircraft structures), it causes liquid metal embrittlement. This reaction slowly eats away the alumin
