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.

Torokira Keychain

Easy craft: glossy jelly keychains! Simple handmade project with 100-yen shop materials. Perfect for at-home time, summer vacation, and free craft or science projects. Great for beginners too. [100-yen DIY]

Do you know those cute accessories with a little doll floating in a tiny plastic bag? You often see them as prizes at festival raffles, but actually, you can make them yourself.

You only need items mostly from a 100-yen shop—like a soft card holder, beads and glitter, liquid laundry starch, and masking tape—so it’s a budget-friendly craft project.

Add cutouts of your favorite character or idol to the decorations, and it instantly becomes merch for your fave! You’ll want to make them for everyone!

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!

Experiment to make clear ice

[Independent Research] An experiment to easily make clear ice in one day! Recommended for elementary and middle school students. [Light] [Reflection]

If you take a close look at the ice in drinks served at shops or the ice cubes sold in stores, they’re beautifully clear.

Meanwhile, the ice you make at home often looks cloudy, doesn’t it? That’s because clear ice contains fewer impurities and is frozen slowly over time.

Once you know the trick, it’s nothing special—but turning this mystery into a science project could be fun.

People often say you can make clear ice by wrapping water in bubble wrap (the cushioning material) and chilling it, but it would be great to run comparative experiments on those conditions.

Ultra-clear ice really draws attention!

Baking Soda and Vinegar Experiment

Independent Research for Middle Schoolers: How to Conduct and Analyze the Baking Soda and Vinegar Experiment (Kei Doyama)

A highly recommended project for anyone looking for a classic, science-focused independent study is the “baking soda and vinegar experiment.” If you’re in middle school, you’ve probably produced various gases in science class.

For example, oxygen is generated by mixing manganese dioxide and hydrogen peroxide.

In the experiment introduced here, mixing baking soda and vinegar produces carbon dioxide.

There are many ways to present it, such as inflating a balloon or a glove with the generated carbon dioxide.

The “baking soda × vinegar” experiment is also a versatile idea that can be adapted into a project like “making different gases using everyday materials.”

Let’s explore the secrets of sound

Here’s an idea for a flute you can make just by connecting straws.

Prepare straws that are all the same thickness and length.

You’ll need 8 straws for the mouthpiece, and since you’ll place spacer straws between them, prepare an additional 7, for a total of 15.

Cut the spacer straws to 5 cm.

The straws that become the flute pipes will vary in length depending on the pitch, so be sure to measure their lengths carefully with a ruler.

After cutting, seal one end of each straw with tape to make it a closed pipe.

Once everything is connected and glued together, it’s done.

Try experimenting with different lengths to see what sounds they make.

I tried expressing sound with salt

[Sound LAB] Great for independent research! We tried representing sound with salt!

Have you ever used a tuning fork in a science class? There’s an experiment where you place two tuning forks side by side with a screen between them and strike one of the tuning forks.

The result shows that sound carries vibrations through the air to the other tuning fork, creating resonance.

How about a free research project where you visualize sound vibrations using salt? The patterns in the salt change with pitch, which is quite fascinating, and you could also study factors like room temperature and differences between instruments that produce the sound.

Doing this research might make you more sensitive to the “don-don” sound of drums!
