What is it about those tiny bubbles that make us happy? I was pondering this sitting in the tub today, trying to sublimate my worries with a bath of raspberry scented bubbles. Don Ho sung about it, we enjoy the leopard pattern of crema on espresso, surfactants are added to shampoos for that luxurious lather (though it is the ingredient that stings our eyes), and it was a food craze for avant-garde science chefs. The bubble is the perfect (most efficient and smallest) form of a solution to enclose a given volume. It’s a happy thought to think about when you’re splashing in the warm water.

Archimedes pondered the very same thing, I wonder if raspberry bubble bath got him to think about it too.
