The 10-Yen Coin Polishing Operation!

Summer Science Project: Which Condiment Makes a 10-Yen Coin the Shiniest? [Research]

Perfect for anyone wanting to do a science project using everyday items! This idea is to find which condiment can make a 10-yen coin the shiniest.

It’s easy! First, gather various condiments.

Ketchup, honey, sugar water, vinegar—anything you have at home is fine.

Put equal amounts of each into paper cups or similar containers along with a 10-yen coin.

Then leave them for five minutes and record the results.

Take photos of the original coin and after soaking it in each condiment, and compare the differences!

gachapon

A gashapon I made for my summer vacation independent research project this year.

They’re the machines you find in front of candy shops or stores where you put in about 100 yen, turn the knob once, and get a toy.

How about making your own original version of one? It could also be fun to create your own unique prizes.

Let’s recreate that thrill and excitement you feel in the moment you turn the gacha machine.

Let’s make cottage cheese

How to make cottage cheese

It seems you can make cottage cheese by adding lemon juice or vinegar to warmed milk! Cottage cheese is a soft fresh cheese and a typical non-aged cheese.

In other words, it’s a light and refreshing cheese.

It might be fun to experiment by changing the amounts and temperature, like a science experiment.

Balloon telephone

[Summer Vacation Independent Study] 10: Let’s Communicate with Balloon Telephones!

I think many of you have tried using a string telephone.

But did you know there’s something called a “balloon telephone”? It’s made similarly to a string telephone: replace the string with a long balloon and insert it into a paper cup.

Then try speaking… Since this experiment requires two people, be sure to try it with someone at home or a friend!

Mating and Spawning of Medaka (Japanese Rice Fish)

Adult Independent Study: Medaka Mating to Spawning

The video title says “adult science project,” but I think it’s an observation that children can easily do as well.

It can be hard to spot the individuality of medaka and other fish, but with careful observation you’ll notice they have expressions, which is fascinating.

Also, by learning how medaka work, you can connect it to studying other, more complex organisms.

Paper Cup Perpetual Calendar

DIY! How to make a perpetual calendar with paper cups — easy!

This is a craft project to make a spinning perpetual calendar using a paper cup.

You’ll create a calendar that never has the wrong weekday and can be used forever with just one paper cup.

Since you can design your own original calendar, it’s a great independent project for people who enjoy making things or drawing.

Let’s make a rainbow!

Let's Learn How Rainbows Work (2): Experiments Edition

Here’s an idea: let’s make that rainbow that appears in the sky after the rain! You might wonder, “Can you really make a rainbow?”—but actually, as long as the conditions are right, you can create one anywhere.

Here are two methods.

The first uses a spray bottle or a hose.

On a clear, sunny day, stand with the sun at your back and spray water—this will create a rainbow.

The second uses a water-filled plastic bottle and a flashlight.

This can be done indoors, so you can experiment even on rainy days! Try making rainbows in other ways, too!
