Rubber band ball

A rubber band ball is a compact cluster of elastic bands, commonly found in offices as a toy and creative tool.

About this subject

A rubber band ball is formed by the gradual accumulation of elastic bands wrapped around each other. While seemingly a simple office object, its construction involves interesting physical principles such as surface tension and material elasticity. The practice of creating rubber band balls is common in workplaces, where bands are often used to secure papers and later discarded, but some employees accumulate them until forming a dense, bouncy sphere.

The largest rubber band ball in the world, certified by Guinness World Records, weighs over 4 tons and was built by Joel Waul in the United States, taking several years to complete. This type of record has popularized the hobby, which has online communities dedicated to sharing techniques and progress. In offices globally, rubber band balls are used as stress relievers or for quick entertainment.

Beyond entertainment, a rubber band ball can have practical uses, such as an improvised stress ball or a small throwing object for office games. There is even a physical phenomenon called the "rubber band ball effect" that studies energy dissipation when multiple layers of elastic material are compressed. Culturally, it represents creativity and patience in repurposing discarded materials.
