LIQUID METAL FROM HELL: BEAUTIFUL, DEADLY, AND READY TO EXPLODE

Meet potassium - a shiny, silvery metal that’s so soft you can slice it with a knife. But don’t get too friendly: it’s wildly reactive, especially with water.

Now add sodium, another alkali metal - when they touch things get weird.

They form a liquid alloy that stays fluid at room temperature and balls up into shiny, floating spheres with insane surface tension.

It’s used as a coolant in nuclear reactors and satellites…but expose it to air or water and it goes full Michael Bay in seconds.
