Preserved foods of the Sengoku period

How to make hyorogan (military ration pills)

In an era when battles raged across Japan, soldiers needed to quickly replenish their nutrition in the brief intervals between fights.

One commonly eaten food at the time was a dumpling-like item called hyorogan.

Since recipes for it can be found, let’s try making it and explore how it was used.

Newton’s cradle

[Science Experiment] Perfect for Independent Research! A Newton’s Cradle You Can Make Using Only 100-Yen Shop Items [Budget-Friendly Craft]

Have you ever heard of Newton’s cradle? It’s a device with about five small steel balls suspended on strings in a row.

When you lift and release one ball at the end, only the ball on the opposite end swings out.

Let’s build one, run various experiments, and compile a report.

Newton’s cradle is related to the law of conservation of momentum and the conservation of mechanical energy, so try changing the conditions—for example, what happens if you lift and release two balls instead of one, or if you change the size of the balls? A nice bonus is that, after the experiments, the Newton’s cradle you built can be displayed as interior decor.

Food self-sufficiency seen through cuisine

Increase the food self-sufficiency rate!

In our everyday meals, the ingredients we use are a mix of items produced in Japan and those from overseas.

This is an attempt to explore that ratio.

Focusing on a few specific menu items will likely make it easier to investigate in detail.

Postage Stamps and the World

World stamps world beautiful stamps collection Estampa Briefmarke Timbre Francobollo

Postage stamps used when sending letters and other mail come in many varieties even within Japan.

Looking around the world, you’ll find countless stamps that reflect each country’s unique characteristics.

Let’s research and compile information on stamps used in other countries.

Unusual musical symbols

Explanation of the Sharp (Accidentals and Derivative Notes) | Beginner’s Piano Performance Intro Blog

Typically, performance markings in sheet music serve as a kind of shared understanding among performers, so seeing a symbol tells you how to play.

However, even in works by famous composers, there are pieces that use unusual, rarely seen performance symbols.

For those who can’t read music, this can be a high hurdle, but there are also plenty of truly “over-the-top!” symbols that make you want to say they’re far too free.

It might be fun just to look for them.

Transparent cute coaster

I tried making cute clear coasters! Perfect for a parent-child craft project over summer vacation, too!

Summer is supposed to be hot, but don’t you feel like the summers lately are getting hotter every year? When it’s hot, we crave cold drinks—so why not make coasters to brighten up your drink time and turn it into a summer science project? You’ll be using two-part resin and other chemicals, so be sure to have an adult or an older sibling help you when handling them.

Aside from working with the chemicals, it’s basically just decorating coasters, so even small children can join in! We’re looking forward to seeing your cool, refreshing coasters!

Original Song – Craft Team STARSS – Craft Team STARSS

Let’s make a steady-hand game using materials from a 100-yen shop and learn about electricity! The materials are: a foam brick, a personal safety alarm, aluminum wire, copper wire, and vinyl tape.

Remove the switch from the circuit board inside the safety alarm and insert and solder the copper wire.

Wrap the copper wire with vinyl tape to cover it.

Shape the aluminum wire however you like, insert it into the foam brick, and connect one end of the copper wire to it.

Now your steady-hand game is complete! When you touch the remaining copper wire to the aluminum wire, the safety alarm will sound.

If the alarm doesn’t sound, it means the electrical circuit from positive to negative isn’t connected.

Check it again.
