DIY speakers

Surpass BOSE! I tried making DIY speakers with a Pringles can!

How about making a speaker that you can plug your smartphone or portable music player into? Building a speaker might sound difficult, but to put it simply, all you need to do is make a hole for your phone—it’s that easy! Use an empty cylindrical container, like one from a snack.

Cut a hole with a utility knife big enough to fit your phone, and loosely stuff some toilet paper inside—then you’re done.

You can add a base so it stands firmly, and decorate the tube to create a cool, one-of-a-kind speaker!

homemade motor

Homemade motor: I tried making a homopolar motor. Making of Homopolar Motor

How about trying to make a homopolar motor yourself? Its strange motion will entertain anyone watching.

All you need are an AA battery, a neodymium magnet, and some copper wire.

Place the battery on top of the magnet, then position a piece of conductive wire so that it loops around.

Strangely enough, the copper wire will start spinning.

Using two wires or bending them into complex shapes makes it even more fun.

With a bit of creativity—like setting up many of them side by side—you can turn it into a unique art piece.

By the way, the copper wire can get hot, so be careful when touching it.

Let’s explore the mysteries of color

Independent Research Helper Kit: Explore the Wonders of Color (Gakken)

This is a science project where you closely observe the colors you usually see.

If it’s just observation, even lower-grade elementary students can do it, and upper-grade students can add analysis, so it’s a recommended project for a wide range of grades.

By using the three primary colors of light and layering sheets to create a color photograph, and so on, it becomes an experiment that produces interesting phenomena.

Let’s make an ultra-rich juice

Science independent research: an experiment to make concentrated juice

In summer, many people have probably experienced freezing a plastic bottle of sports drink and, when sipping the partially melted liquid, feeling that it tastes “stronger than usual!” Let’s make this phenomenon the theme of a science project: What mechanism causes it? The key is a phenomenon called freezing point depression.

Solutions containing substances like sugar freeze later and melt sooner than pure water.

Based on this, you can investigate and summarize how the perceived increase in flavor strength differs depending on the type of beverage you freeze.

Making transparent eggs

Summer science project: Make transparent eggs using vinegar [Research]

Suddenly, but do you know what happens if you put a raw egg in vinegar? Believe it or not, it turns into a transparent egg.

It looks a bit swollen, and when you touch it, it feels soft and squishy.

Try carefully observing the process from the moment you put the egg in until it changes.

You could also study why this happens.

By the way, the transparent egg can be easily popped with a toothpick.

The satisfaction of popping it is one of the highlights of this experiment—you’ll probably want to pop more.
