Here's a curious thing that happens when you try mixing liquids that won't chemically blend, like water and oil π§ͺ On Earth, oil floats on top of water because of the difference in density. In space, there's no weight from gravity, so that natural separation never happens. The two liquids stay mixed together as a floating suspension of droplets, until rotation steps in: spin the container, and inertia pushes the denser water outward while the oil gathers toward the center ππ

Another way to think about Trump announcement today: If he increased US diesel imports from Canada by 4%, he would gain as much fuel as from this Russia deal. But the Canadians are global super-villains, so who wants to buy from them when you could enrich Putin instead?
