I am Kuwako Ken, your Science Trainer. Every day is an experiment.<\/strong><\/span><\/p>\n

The “light” we see every day\u2014wouldn’t it be exciting to learn that its true identity is actually a magnificent bundle of rainbows, made up of many colors?<\/p>\n

In this article, I’ll show you how to make a magical “Spectroscopy Mask” that lets you peek into the beautiful world hidden inside light, along with the scientific secrets behind it. This is a fun and educational science craft modeled after Fukuoka’s unique souvenir, the “Niwaka Senpei” (a traditional cracker)<\/a>!<\/p>\n

The True Identity of Light: A Rainbow?<\/h3>\n

Sunlight and light from a bulb look like a single white or yellowish color at first glance, don’t they? However, that light is actually a complete mixture of all seven rainbow colors: red, orange, yellow, green, blue, indigo, and violet. The process of separating this light into its color components is called dispersion (Bunko)<\/b>, and the resulting band of colors is known as the spectrum<\/b>. The reason we see a rainbow after the rain is that tiny water droplets in the air act as prisms, dispersing the sun’s light.<\/p>\n

This time, we’ve made a mask using the magical item, the “Diffraction Sheet”<\/b>, which lets you easily experience this phenomenon of “dispersion”<\/a>.<\/p>\n

Let’s Make a Spectroscopy Mask from “Niwaka Senpei”!<\/h3>\n

The motif for our mask is the super cute, droopy-eyed “Niwaka Senpei” cracker, a famous souvenir from Fukuoka. By utilizing its humorous expression, all you have to do is cut out the eye holes and paste the Diffraction Sheet over them\u2014and voil\u00e0! Your original spectroscope is complete! Put this on and peek at the world; your everyday view instantly transforms into a fairytale land of rainbows.<\/p>\n

I tried drawing various patterns on the mask, but the grasshopper design combined with the face mask turned out to be particularly funny.<\/p>\n

The original template data for the mask is available here, so please feel free to download it and create your very own Spectroscopy Mask!<\/p>\n

Let’s Observe Different Kinds of Light!<\/h3>\n

Once you have this mask, you’re officially a “Light Detective.” Let’s observe the spectrum of various lights inside your home and around town.<\/p>\n
