Most of us encounter soap on a daily basis. Consequently, we tend to take some of its more interesting aspects for granted. For example, why do soap bubbles form? It might seem like something that is intuitive. Water + Soap = Bubbles. However, the real answer is a bit more complicated than that. To answer the question, we need to turn to chemistry.

Soap molecules have two ends, and they are a bit like magnets in that the ends have different properties. One end likes to stick to water while the other end is repelled by water. When you make a bubble, it is because the ends of the soap that stick to water are all pointed towards the water and the ends that repel the water are pointed away In this sense, the soap molecules are “surround” the water molecules. So the surface of a soap bubble is just a thin layer of water that is squished between soap molecules.

Bubbles form into circles or, more accurately, spheres because this shape requires the least amount of soap (and thus energy) to maintain.

You can freeze bubbles if it is a really cold day. If you want to capture them on your camera, you will need to blow the bubbles slowly and try to make them large. The smaller ones freeze faster and are harder to capture an image of.

Learn how you can manipulate the bubbles to do some more awesome experiments in the videos below. And be sure to check out the online store for Kelly Images and Photography, where you can get these awesome prints.
