That little jolt running through your fingertip is a familiar phenomenon that often happens when the air is dry. The truth is, that &#8220;zap!&#8221; is the work of a powerful, invisible force: electric power. Wouldn&#8217;t it be exciting if you could control this unseen power with your own hands?<\/p>\n<p>The experiment we&#8217;re introducing today uses the power of static electricity to seemingly cast a spell on a drinking straw. We call it &#8220;The Moving Straw.&#8221; You barely need any special tools. Let&#8217;s experience the mysterious world of static electricity together!<\/p>\n<h3>What You&#8217;ll Need<\/h3>\n<p>A small block of wood, a nail, a flexible drinking straw, and tissue paper.

The True Identity of the Invisible Force<\/h3>\n<p>It looked like the straw moved by itself, but of course, it wasn&#8217;t magic. This is the power of static electricity. When two objects are rubbed together, tiny particles of electricity called electrons can move from one object to the other. In this experiment, we rubbed the straw and the tissue paper. Between these two materials, tissue paper tends to lose electrons, and the straw tends to gain them.<\/p>\n<p>As a result, the tissue paper ends up in a positive (+) state, having lost electrons, and the straw ends up in a negative (-) state, having an excess of electrons. This state of electrical imbalance is called electrification or being charged. (By the way, if you rub a rubber balloon with tissue paper, it also tends to gain electrons, becoming negatively (-) charged, just like the straw.)<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-34471 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/53333d5fb483dc49cee16bbbe028858c-1.jpg\" alt=\"\" width=\"390\" height=\"173\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/53333d5fb483dc49cee16bbbe028858c-1.jpg 1120w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/53333d5fb483dc49cee16bbbe028858c-1-300x133.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/53333d5fb483dc49cee16bbbe028858c-1-1024x455.jpg 1024w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/53333d5fb483dc49cee16bbbe028858c-1-768x341.jpg 768w\" sizes=\"auto, (max-width: 390px) 100vw, 390px\" \/><\/p>\n<p style=\"text-align: center;\">Triboelectric Series (Reference: Kuwako Ken &amp; Takeda Junichiro, Kagaku Kentei Official Workbook Grades 5 &amp; 6, Kodansha)<\/p>\n<p>The chart above is called the Triboelectric Series, which ranks materials by how likely they are to become positive or negative. The combination of materials you rub together determines which one becomes positive. Now, electricity has a crucial rule. It is&#8230;<\/p>\n<ul>\n<li>Like charges (positive and positive, negative and negative) repel each other (repulsive force).<\/li>\n<li>Unlike charges (positive and negative) attract each other (attractive force).<\/li>\n<\/ul>\n<p>It&#8217;s similar to the relationship between the North and South poles of a magnet.

The straw moves as if pulled towards the tissue paper. Through this experiment, we were able to experience the invisible electric force of attraction and repulsion through the movement of the straw.<\/p>\n<h4>Why Does It &#8220;Suddenly&#8221; Start Moving When You Get Close?<\/h4>\n<p>Didn&#8217;t you notice another interesting detail? When you bring the tissue or balloon closer, nothing happens when they&#8217;re far away, but the moment you cross a certain distance, the straw must have &#8220;suddenly&#8221; spun into motion. The truth is, this static electricity force (called Coulomb&#8217;s Force) is deeply related to the distance between the two objects.<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-35232\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2020\/02\/229be853be4011d496edf605e5a56d6c.jpg\" alt=\"\" width=\"111\" height=\"50\" \/><\/p>\n<p>To put this formula very simply, it shows that the closer you get, the exponentially stronger the force becomes. For example, if you halve the distance (1\/2), the force becomes a whopping 4 times (2&#215;2) stronger. If the distance is reduced by a third (1\/3), the force becomes 9 times (3&#215;3) stronger! That&#8217;s why the force is too weak to move the straw while you are bringing it closer from far away, but the moment you cross a certain point (distance), a strong enough force &#8220;suddenly&#8221; generates, making it look like the straw jumped into motion.<\/p>\n<h3>If You Use a Static Electricity Generator, You Can Do These Amazing Experiments!<\/h3>\n<p>Static electricity is fun even just by rubbing things, but using a dedicated Static Electricity Generator (Van de Graaff generator) allows for even more powerful and astonishing experiments. We have also shared other interesting experiments using the static electricity machine (Van de Graaff). This includes experiments we conducted on a TV program with celebrities like Suzu Hirose, Ryohei Suzuki, Yasuko, and Chocolate Planet&#8217;s Osada and Matsuo.
