Now, scientists have explained the physics behind why some paper is more likely to slice through skin.<\/p>\n<p>Physicist Kaare Jensen was part of a team that set up experiments to study this. They used a gelatin replica of human tissue. Jensen works at the Technical University of Denmark in Kongens Lyngby. A thickness of <a href=\"https:\/\/journals.aps.org\/pre\/accepted\/aa072Kc5A071ae0708c39799a466b7d26e3ac2a0e\" rel=\"noopener\">around 65 micrometers (not quite 3 thousandths of an inch) was the sweet spot<\/a> for paper cuts, they found. (Or you might call it the sore spot!) Their findings got posted June 19 in <em>Physical Review E<\/em>.<\/p>\n<p>A thin sheet of paper wouldn\u2019t cut; it would bend instead. Thicker paper made a dent in the gelatin but couldn\u2019t break its surface. Like a dull knife blade, it couldn\u2019t apply enough force over a small enough area of the material to pierce it.<\/p>\n<p>The most treacherous paper tested was the kind used in old-fashioned dot matrix printers. Good news for fingers everywhere: That paper isn\u2019t used much anymore. Magazine paper ranked a close second in the scientists\u2019 tests.<\/p>\n<p>The slicing angle also mattered. Pressing the paper\u2019s edge straight down into the gelatin was less likely to cause a cut than if the paper\u2019s path angled across and down.<\/p>\n<h2 class=\"wp-block-heading\">Progress on the cutting edge<\/h2>\n<p>Next, the researchers put paper\u2019s slicing powers to use. They designed a <a href=\"https:\/\/www.snexplores.org\/article\/explainer-what-3-d-printing\">3-D printed<\/a> tool they call the Papermachete. Loaded with a strip of printer paper, the tool becomes a single-use knife. The paper blade can cut into cucumber, pepper and apple. It can even cut chicken. The tool could be a low-cost option for prepping some foods.<\/p>\n<p>Next, the researchers plan to study more realistic, finger-shaped materials, rather than flat sheets of gelatin, says Jensen.<\/p>\n<p>No human fingers were harmed in the making of the study. \u201cIdeally, you would want some test subjects,\u201d Jensen says. &#8220;But it\u2019s hard to find volunteers.\u201d<\/p>\n<p><br \/>\n<br \/><a href=\"https:\/\/www.snexplores.org\/article\/science-of-paper-cuts\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tiny as they are, paper cuts can cause real pain.
