POP! A Book About Bubbles

Dip the plastic wand into the soap solution. Hold it up to your mouth. Now blow. Phhhh! You've made a bubble!

Watch it float higher and higher. The bubble shimmers in the sun. Up it goes, up, up, then pop! It disappears.

You can blow small bubbles or big ones. You can blow one bubble or hundreds of bubbles. You can't blow square bubbles or flat bubbles. All bubbles are round.

Bubbles are air trapped inside liquid. The liquid you put your bubble wand into is made of waterand soap. Sometimes it has a little corn syrup too. It is sticky. It sticks to the floor if you spill it. It sticks toyour fingers when you touch it. And it sticks to the plasticbubble wand. It sticks and it stretches. It stretches acrossthe round hole on the end of the bubble wand.

When you blow into the wand, you make air move. If you blow slowly, you cansee how the air makes thesoap on the wand start to As you blow harder, thesoap stretches and stretchesuntil it can't stretch anymore. Finally it snaps free. Thesoap shuts around theair inside it. There it is! A bubble!
