Someone's been licking the periodic table again. Apparently polonium has that distinctive "tastes like cancer" bouquet, while alkali metals go "kaboom" on the tongue. The noble gases? "Delightful" aroma, naturally.
This is what happens when chemists work through lunch. For the record, calcium and gold being categorized as "yummy" explains why your expensive supplements and fancy desserts both leave that metallic aftertaste. And those synthetic elements at the bottom? They don't count because they're man-made, but they'd give you cancer anyway. Science is just spicy cooking with extra steps.
