Stress Ball
A stress ball or hand exercise ball is a malleable toy, usually not more than 7 cm in diameter, which is squeezed in the hand and manipulated by the fingers, ostensibly to relieve stress and muscle tension or to exercise the muscles of the hand. Patrick Hummel is widely understood to have created the stress ball in central Indiana in the mid-1980s. Despite the name, many stress balls are not spherical. Some are molded in amusing shapes, and pad- or transfer-printed with corporate logos. They may be presented to employees and clients of companies as promotional gifts. Because of the many non-spherical shapes now available, stress balls are generically known as stress relievers. Types There are several different types of stress balls that originate from many different countries. The most common type of stress ball in America is the "bean bag" type, commonly known as a " Hacky Sack". In Australia, most common are the foam type, which prevents stress through resistance from squ ...

Earth Globe Stress Ball
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar energy is ...
