For an even more vivid view, try shining an LED light or your smartphone\u2019s flashlight through the paper cup.<\/p>\n<p>Why does transparent tape suddenly show colors? Plastic films like clear tape have a property called birefringence, which changes how light waves travel through them. When this happens between two polarizing plates, only specific colors are highlighted and reach our eyes.<\/p>\n<p>The color patterns change infinitely depending on how you layer the tape. Feel free to add more tape or change the angles to find your favorite color combination!<\/p>\n<p>By the way, here is a large-scale exhibit of polarizing plates at the Science Museum. It&#8217;s a great way to experience how polarization works on a big scale!<\/p>\n<p><iframe loading=\"lazy\" title=\"\u504f\u5149\u677f\u3092\u4f7f\u3063\u305f\u4e0d\u601d\u8b70\u306a\u5c55\u793a\u7269\uff20\u79d1\u5b66\u6280\u8853\u9928\" width=\"1140\" height=\"641\" src=\"https:\/\/www.youtube.com\/embed\/dFDAkLlN97Y?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<h3>What exactly is a Polarizing Plate?<\/h3>\n<p>The secret to this kaleidoscope lies in a mysterious black film called a polarizing plate. In high school physics, these are famous for experiments proving that light is a transverse wave.<\/p>\n<p>Light actually travels as a wave. Imagine it as a &#8220;noisy wave&#8221; vibrating in every direction\u2014up, down, left, right, and diagonally\u2014as it moves forward. A polarizing plate acts like an invisible set of blinds that forces light waves to &#8220;line up.&#8221;<\/p>\n<p>When light passes through a &#8220;vertical blind,&#8221; only the waves vibrating vertically can get through. If you place a &#8220;horizontal blind&#8221; immediately after it, what happens? The vertical waves can&#8217;t pass through the horizontal blinds, and the light is completely blocked, leaving everything pitch black.<\/p>\n<p>Because of this orientation, rotating two stacked polarizing plates can either let light through (when the blinds align) or block it out (when they are perpendicular).<\/p>\n<p>This technology is very useful in our daily lives. When light reflects off water, the vibrations align, creating that harsh glare. Polarizing filters (PL filters) on cameras cut this glare, allowing you to see clearly into the water.<\/p>\n<h3>Why does Clear Tape create a Rainbow?<\/h3>\n<p>&#8220;Okay, polarizing plates block and allow light. But why the colors?&#8221;<\/p>\n<p>This is where our second secret weapon comes in: clear cellophane tape. Cellophane tape has a hidden power: it &#8220;twists&#8221; the vibration direction of light as it passes through. Even more interestingly, it twists different colors of light at slightly different angles!<\/p>\n<p>In this kaleidoscope, we have the first polarizing plate, the clear tape, and then the second plate. Light lines up through the first &#8220;blind,&#8221; then hits the tape. Red light gets twisted to angle A, blue light to angle B, and so on.<\/p>\n<p>When that light reaches the second &#8220;blind&#8221; at the exit, some colors are allowed through while others are blocked. As a result, specific colors are boosted or cancelled out, reaching our eyes as a beautiful rainbow!<\/p>\n<p>The patterns change infinitely just by layering the tape because each layer changes how the light is twisted.<\/p>\n<p>Using these mysterious plates, we\u2019ve made an eco-friendly and beautiful kaleidoscope out of simple household items like paper tubes.
