A pillow fight is a common game mostly played by young children (but can also occur with teens and adults) in which they engage in mock physical conflict, utilizing pillows as weapons.
Many times pillow fights occur during children sleepovers. Since pillows are soft, injuries rarely occur. The heft of a pillow can still knock a young person off balance, especially on a soft surface such as a bed, which is a common venue. A useful technique in a pillow fight is to bundle the nibs. In earlier eras, pillows would often break, shedding feathers throughout a room. Modern pillows tend to be stronger and are often filled with a solid block of artificial filling, so breakage occurs far less frequently. An organized pillow fight will usually feature feathers due to its traditional value.
