The joke here is delightfully nerdy. Gallium (Ga) has a melting point of just 29.8°C (85.6°F), which means at 40 degrees outside, it would literally melt in your hands. While most metals require furnaces and blowtorches, gallium just needs a warm summer day. Chemistry students know the joy of watching a solid metal spoon dissolve into liquid while stirring hot tea. It's basically the ice cream of the periodic table—except instead of "I scream, you scream," it's "I melt, you clean up the silvery puddle from your lab bench."
