It's colder than outside at night

It's colder at night than during the day. The sky turns red when the sun sets. A soap bubble bursts when it touches something. Cream stiffens when whipped. Potatoes become soft when cooked, while an egg becomes hard. The head on a freshly poured Pilsner lasts. A mosquito bite itches. Everyday phenomena that everyone knows, yet hardly anyone can explain.
