Let’s learn about bubbles

What better activity is there for a beautiful summer day?

Blowing soap bubbles is easy. Blowing big soap bubbles is a bit more tricky. And there’s a secret to picking up a bubble — use wet hands.

Bubbles are everywhere. You just need to know where to look. There’s the obvious place — the soap bubbles in your bath. There are also bubbles in your body. They’re responsible for your cracking knuckles. The gems in a ring might have bubbles, called inclusions. Going farther out, humpback whales use bubbles to hunt. And scientists figured out a way to heal wounds with bubbles.

But the best bubbles, at least on a sunny summer day, are probably the bubbles you blow in your own backyard. Scientists have found these bubbles to be alluring, too. They’ve figured out the best way to blow perfect bubbles, and the secret recipe for making huge ones. They’ve also listened in on bubble bursts to figure out the physics that underlie the gentle “pfttt” that accompanies a bubble’s demise.
