Bubbles attract a lot of attention. They are pretty, fun and fascinating. Bubbles can also be used to awaken a girl’s fascination with science.
Bubbles are made up of two thin soap molecules and water. In most cases, bubbles are filled with air; however, some bubbles contain gases like carbon dioxide or hydrogen. The soap molecule’s hydrophilic (water loving) head faces the water while the hydrophobic (water fearing) hydrocarbon tail extends away from the water layer.
Other Scientific Facts About Soap
Soap contains a carboxylate group that reacts with calcium and magnesium ions. Glycerin, C3H5(OH)3, extends the life of a bubble by forming weaker hydrogen bonds with water and slowing down its evaporation.
