Every day is an experiment!<\/strong><\/span><\/p>\n<p>That mysterious &#8220;snap&#8221; and &#8220;crackle&#8221; when you take off your sweater on a cold winter day. The way your hair stands up poof! after rubbing it with a plastic ruler. Everyone has experienced these things, right? These phenomena, which seem almost like magic, are actually caused by an invisible, tiny force called static electricity.<\/p>\n<p>Today, I&#8217;m going to introduce a super simple experiment that will help you &#8220;visualize&#8221; the power of static electricity that surrounds us every day. Just by hanging a balloon from the ceiling, you can clearly see the effects of static electricity&#8217;s force.

Something mysterious might happen!<\/p>\n<h3>Unraveling the Experiment&#8217;s Mechanism!<\/h3>\n<p>You should have observed some strange movements in the experiment\u2014the balloons either running away or sticking together. The key to this phenomenon is the positive (+) and negative (-) charges that all matter possesses.<\/p>\n<p>Normally, matter is electrically neutral because it has an equal amount of positive and negative charge. However, when you rub two different materials together, electrons (which carry a negative charge) can move from one object to the other. This is the true identity of static electricity.<\/p>\n<p>Whether electrons are likely to move is determined by the type of material. The order of how easily materials become charged is shown in this chart, called the Triboelectric Series.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-34495 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/b7c1f686bee5c9bc9e3f5c91e2083106.jpg\" alt=\"\u5e2f\u96fb\u5217\u306e\u56f3\" width=\"514\" height=\"234\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/b7c1f686bee5c9bc9e3f5c91e2083106.jpg 848w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/b7c1f686bee5c9bc9e3f5c91e2083106-300x137.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/b7c1f686bee5c9bc9e3f5c91e2083106-768x350.jpg 768w\" sizes=\"auto, (max-width: 514px) 100vw, 514px\" \/><\/p>\n<p style=\"text-align: center;\">From my book, &#8220;Science Test Grade 3 &amp; 4&#8221; (Kodansha, Ken Kuwako)<\/p>\n<p>The further apart two materials are on this list, the more likely they are to generate static electricity when rubbed together. For example, when you rub a balloon (Rubber) with a handkerchief (let&#8217;s assume it&#8217;s Silk), electrons will move from the silk (on the right) to the rubber (on the left) in the Triboelectric Series.<\/p>\n<p>As a result, the balloon gains many electrons and becomes negatively charged, while the handkerchief loses electrons and becomes positively charged.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-34874 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/03\/1490f0691670223ef403427a3fd23461.jpg\" alt=\"\u98a8\u8239\u3068\u5e03\u306e\u9593\u306e\u96fb\u5b50\u306e\u79fb\u52d5\" width=\"302\" height=\"223\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/03\/1490f0691670223ef403427a3fd23461.jpg 636w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/03\/1490f0691670223ef403427a3fd23461-300x222.jpg 300w\" sizes=\"auto, (max-width: 302px) 100vw, 302px\" \/><\/p>\n<p>Electricity follows a very important rule:<\/p>\n<p>Charges of the same kind (negative &amp; negative, positive &amp; positive) repel (push away).<\/p>\n<p>Charges of different kinds (positive &amp; negative) attract (pull toward each other).<\/p>\n<p>Now, keeping this rule in mind, let&#8217;s look at the results of our experiment&#8230;<\/p>\n<p>\u3010Result 1\u3011When you bring two rubbed balloons close together&#8230;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-34723 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/cb42cbb6b7e61aa1f0b20a77b175f692.jpg\" alt=\"\u53cd\u767a\u3057\u3042\u3046\u4e8c\u3064\u306e\u98a8\u8239\" width=\"374\" height=\"277\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/cb42cbb6b7e61aa1f0b20a77b175f692.jpg 774w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/cb42cbb6b7e61aa1f0b20a77b175f692-300x222.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/cb42cbb6b7e61aa1f0b20a77b175f692-768x570.jpg 768w\" sizes=\"auto, (max-width: 374px) 100vw, 374px\" \/><\/p>\n<p>Since both balloons are negatively charged, they repel each other, essentially shouting, &#8220;Go away!&#8221; Isn&#8217;t it fascinating that a force can work without even touching?<\/p>\n<p>\u3010Result 2\u3011When you bring the rubbed handkerchief close&#8230;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-34724 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/4d22b06d3ba12de9501c88aaaa31087e.jpg\" alt=\"\u98a8\u8239\u3068\u5e03\u304c\u5f15\u304d\u5408\u3046\u69d8\u5b50\" width=\"338\" height=\"260\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/4d22b06d3ba12de9501c88aaaa31087e.jpg 800w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/4d22b06d3ba12de9501c88aaaa31087e-300x231.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/4d22b06d3ba12de9501c88aaaa31087e-768x591.jpg 768w\" sizes=\"auto, (max-width: 338px) 100vw, 338px\" \/><\/p>\n<p>This time, you have the negative balloon and the positive handkerchief, so they attract each other, like saying, &#8220;I love you!&#8221;<\/p>\n<p>\u3010Result 3\u3011When you bring yourself close to the balloon&#8230;<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-34727\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/444a008c510e8e439128d1983ca661b4.jpg\" alt=\"\u98a8\u8239\u3067\u4f53\u3092\u3053\u3059\u308b\" width=\"260\" height=\"274\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/444a008c510e8e439128d1983ca661b4.jpg 518w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/444a008c510e8e439128d1983ca661b4-285x300.jpg 285w\" sizes=\"auto, (max-width: 260px) 100vw, 260px\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-34725 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/14b9747b46468dcc35f84330ddccd030.jpg\" alt=\"\u4eba\u3068\u98a8\u8239\u304c\u5f15\u304d\u5408\u3046\" width=\"358\" height=\"310\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/14b9747b46468dcc35f84330ddccd030.jpg 744w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/14b9747b46468dcc35f84330ddccd030-300x260.jpg 300w\" sizes=\"auto, (max-width: 358px) 100vw, 358px\" \/><\/p>\n<p>Astonishingly, you were also attracted to the balloon!
