The Bubble Trampoline

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 and the air is trapped on the inside. Bubbles are very delicate and they don’t last very long before they pop.  They pop as soon as most of the water in the bubble evaporates. Poof!   

 

You can make bubbles with lots of things like straws, strings, cups, and paper towel tubes.   You just need something to hold the bubble film while you blow some air into it.  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 is 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.
