The Story Behind Japan's Vibrant Manhole Covers

In most countries, manholes are an ugly (yet necessary) public convenience, but in Japan, they’re colorful works of art. There, the utilitarian metal covers are adorned with unique designs and feature local attractions or symbols, like cherry blossoms, Mount Fuji, or the Yokohama Bay Bridge.

According to The Japan Times, municipalities allegedly started decorating manhole covers in the 1980s, after officials told them that the eye-catching utility vault lids could help enhance the public image of Japan’s sewerage system. Today, manhole cover manufacturers create the designs, and submit them to local administrators. In turn, they select a winning design, and commission manholes in its likeness.

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

You can opt for three larger rooms if you're willing to skip the kitchen and bathroom.Allwood/Amazon

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

Would you fly in this?
Would you fly in this?

As it turns out, being destroyed by the very thing you create is not only applicable to the sentient machines and laboratory monsters of science fiction.

In this episode of The List Show, Mental Floss editor-in-chief Erin McCarthy takes us on a sometimes tragic, always fascinating journey through the history of invention, highlighting 13 unfortunate innovators whose brilliant schemes brought about their own demise. Along the way, you’ll meet Henry Winstanley, who constructed a lighthouse in the English Channel that was swept out to sea during a storm … with its maker inside. You’ll also hear about stuntman Karel Soucek, who was pushed from the roof of the Houston Astrodome in a custom-designed barrel that landed off-target, fatally injuring its occupant.

And by the end of the episode, you just might be second-guessing your secret plan to quit your day job and become the world’s most daredevilish inventor.
