Stress ball

<h2 id="types">Types</h2>

<p>There are several types of stress balls that originate from many countries. The most common type of stress ball in America is the "<a href="/facts/Bean_bag/NlCng1GK">bean bag</a>" type, commonly known as a "<a href="/facts/Hacky_sack/Pe58Gbhg">Hacky Sack</a>." In Australia, most common are the foam type, which prevents stress through resistance from squeezing the ball. Chinese-form balls are known as the <a href="/facts/Baoding_balls/egasgopd">Baoding ball</a>; unlike others, these are not squeezable as they are solid and come in pairs, allowing users to roll them together to make a soothing sound and a smooth sensation feeling in one's hands.<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a> They come in a variety of shapes and sizes.
</p>

<p>Some stress relievers are made from closed-cell polyurethane <a href="/facts/Foam_rubber/zlN6B0vS">foam rubber</a>. These are made by injecting the liquid components of the foam into a mold. The resulting chemical reaction creates <a href="/facts/Carbon_dioxide/xGzpppEp">carbon dioxide</a> bubbles as a byproduct, which in turn creates the foam.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a>
</p><p>There are also mochi <a href="/facts/Squishy/cxmoJWao">squishies</a>, which are small, slightly sticky, usually shaped like cute animals or fruits/vegetables, and are made of silicone. They get their name from <a href="/facts/Mochi/NHThxFKa">mochi</a>, a Japanese dessert.
</p><p>Stress balls, especially those used in <a href="/facts/Physical_therapy/q24XDqHF">physical therapy</a>, can also contain <a href="/facts/Gel/gBFE0s9G">gel</a> of different densities inside a rubber or cloth skin. Another type uses a thin rubber membrane surrounding a fine powder. The latter type can be made at home by filling a balloon with <a href="/facts/Baking_soda/S9oSol0R">baking soda</a>. Some balls similar to a <a href="/facts/Footbag/Pe58Gbhg">footbag</a> are marketed and used as stress balls.
