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

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

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.

Making battlefield midday meals in the Sengoku period

I think making and eating jinchūshoku called hyōrōgan—field rations actually eaten on battlefields during the Sengoku period—will spark interest in history.

The ingredients are easy to gather at any supermarket, and even those who aren’t good at cooking can make them with no trouble.

Aroma Fragrance

[Summer Vacation Independent Research][Summer Vacation Craft][DIY] Done in 5 minutes! Super easy! Recommended for elementary school girls! How to make an aroma fragrance (air freshener) using a cold pack

If you’re looking for an easy, summery craft, I recommend making an aroma fragrance jar! Prepare a jar, gel ice packs, blue food coloring, essential oils, and decorations like marbles or seashells.

First, fill the jar about one-third full with the gel from the ice packs and add the food coloring to tint it.

Once the color is set, add more gel and a few drops of your favorite essential oil.

Finally, add the decorations and put the lid on—you’re done! Using blue food coloring with marbles or seashells makes it look like you’ve captured the sea inside the jar.

Try creating one with your favorite theme!
