✨ Did you know that in the vacuum of space, metals can bond together without heat? 🤯 This incredible phenomenon, known as cold welding, occurs when two pieces of the same metal touch. With no air or moisture to create an oxide layer, their atoms see each other as one! This mind-blowing fact isn’t just a cool science tidbit—it presents real challenges for engineers and astronauts. 🛠️ Imagine if metal parts on a spacecraft accidentally touch and fuse together! It could lead to equipment failures
