What is a Soap Bubble?
It is a very thin layer of water that forms between two layers of soap molecules. The soap molecules have one end that repels water, and the other that attracts it. Both have inner and outer surfaces. Without the molecules, the bubble would most likely break apart into droplets of water. Surface tension (as well as pressure) are what makes bubbles spherical in shape.

=Pressure= The reason behind how a bubble can form (or is mostly formed) into a sphere is because it has equalpressure on the inside and as well as the outside. Thus, having a surface with zero. Dueto the differencein the outside and inside pressures,it is a surface of constant. If you think of it this way, the soap bubble is technically surrounded by just water and soap. The air that is trapped inside after blowing the bubble will had added air pressure inside of it and the air surrounding the bubblewill add a pressure to the soap from the outside. So there will be pressure from both inside and outside surfaces of the bubble. However, the pressure inside the bubble would always be greater than the pressure that is exerting on the outside. The bigger the bubble, the lower the pressure. The smaller the bubble, the higher the pressure.

=Light= The thinness of the film of soap is whether showing luminous colors that seem to change when seen from different angles is clearly visible or understood. The light that reflects on towards it is reflected from both the inner and outer surfaces of the bubble. When a ray of light hits the outside surface of the buble, a part of it is reflected off immediately, while the other part is transmitted inside of the bubble. Once reaching the inside surface, the light is then being sent back towards the outside surface of the bubble.

=States of Matter= What state of matter would a soap bubble be in? Considering the fact that it is clearly made out of water and well...soap, would it be referred to as a liquid or a solid? Would it be a gas or a plasma? To make matters more easier, a soap molecule is consisted of long chains, having an end that likes OIL and another that likes WATER. The thing film of soap that creates the outer most shell of the bubble are coated with a mono-layer of soap molecules with the side that prefers OIL, facing away from the side that likes WATER. So technically, it is directly produced form a liquid state, but it retains its form until a strong force acts upon it, hard enough to break it. Gas... bubbles are formed when water (or another liquid substance) are heated up and then turned to gas. When water on a fire heats up at the bottom of a container that water turns to gas before the water at the top. Since gas is lighter than water it rises in the form of a bubble and pops at the surface So bubbles are in the state of gas.
