Abstract

Do you like playing with bubbles? Almost every kid loves to blow bubbles – and wishes that their bubbles don’t pop or evaporate so quickly! This science fair project was performed to determine if adding other substances to a bubble solution can help the bubbles last longer. Testing was done by adding corn syrup, sugar water, glycerin and lemon juice the to the bubble solution.

Hypothesis

Soap bubbles made from solutions containing glycerin will last the longest.

Scientific Terms

Glycerin, dissolve, dehydration, evaporation

Background

Soap bubbles

Blowing soap bubbles has always been enjoyable to children. . Bubbles however, usually do not last long and burst easily when they come into contact with another object. Sometimes, they simply dry up. Bubbles are formed because of the surface tension of a liquid. A bubble made with a pure liquid such as water is not stable. Adding soap to water helps to stabilize the bubble.

Bubbles are very light because they are made up of air and a thin layer of fluid that forms a sphere around the pocket of air. They float easily. A slight breeze will be enough to lift the bubble up into the air and cause it to float until it bursts when it collides into another object or when the layer of water on the exterior of the bubble has evaporated.
