What is bubble?

A bubble is like a tiny, round balloon that you can blow and watch float away.

Imagine you have a straw, and you put it in a cup of soapy water. When you blow into the straw, the soap and water stretch out to make a bubble, a soft, shiny circle that floats in the air before popping with a snap!

When you blow, you're giving the bubble some energy, like when you push a toy car and it rolls across the floor. The soap helps keep the bubble from breaking too quickly, just like how a bubble wrap keeps your toys safe when you pack them for a trip.

Bubbles pop because the air inside wants to escape, and the soap can't hold on any longer, it's like when you let go of a balloon, and it floats up until it's too light to stay tied.

You can even make bubbles with different shapes if you use special tools, just like how you can draw circles or squares with crayons!
