Скачать или смотреть Bubbles are an Interesting Mixture of Materials

Bubbles are an interesting mixture of materials. They are usually made out of a blend of soap, water, and air. The soap and water form the outside surface of the bubble while the air is trapped on the inside. As you know, bubbles are very delicate and they don’t last very long before they pop.

Bubbles tend to be round, or spherical, in shape because this shape helps them to be more stable. Spherical shapes use a minimal amount of surface area to enclose the volume of air that’s trapped inside. Surface area is the amount of space that an object occupies on the outside. The less surface area on the outside of an object, the more strong and stable it tends to be.
You can make a super cool and sorta strange bubble using the cut off ends of a two liter bottle. And with a little bit of practice, you can even get it to dance.
