Remaking a 100-yen shop clock

Remake a 100-yen shop clock! Clip clock 👍✨Summer Vacation Craft#Summer Vacation Workshop#100-yen shop DIY#100-yen shop arrangement

♪ Original song – Nanmo-kun – Nanmo-kun

The part you can see from the back of a table clock or wall clock—the section with the battery compartment and the knob for setting the time—is called the movement.

You could say it’s the heart of the clock.

In fact, clock movements are sold on their own at 100-yen shops and home improvement stores, and you can use them to make your own original clock! If you’re good at woodworking, try starting from scratch by buying a wooden board and cutting a groove to fit the movement.

If that’s not your strong suit, there are also assembly kits with pre-cut grooves available, so you can use those instead.

Milk Carton Rolling Tower

Let’s reuse empty milk cartons to make a fun rolling tower where a ping-pong ball tumbles down! Cut the milk cartons and connect two of them to create a long cylindrical base.

Make holes and slits in paper plates, attach them in a stepped arrangement, and adjust the angles so the ball rolls smoothly through.

Add slits to the side of the cylinder so the ball won’t stop midway and will drop all the way to the bottom.

If you wrap the whole thing with a tube-shaped cover made from a clear file, the ball won’t fly out and it’s safer to play with.

A bonus is that kids can learn about gravity and incline through the speed of the rolling ball and the fun sounds it makes.

It’s an eco-friendly idea that uses recycled materials to create a moving, interactive project.

A piggy bank that helps you save while having fun

Let’s use Daiso’s 3-tier drawer case to make a fun, game-like piggy bank over summer break.

First, flip the second and third drawers upside down and reassemble them so the flat sides face the front.

Next, cut corrugated plastic (plastic cardboard) into any shapes you like and attach it to the outside of the drawers to create a design that looks great.

Inside, apply double-sided tape so coins pause partway and drop slowly as they travel down.

With a piggy bank you made yourself, saving money becomes fun and easier to turn into a habit.

It’s a unique, practical idea that can change your everyday life through creativity and ingenuity.

How about this for your summer vacation project?Summer Vacation Craft#Summer VacationDesk lamp

Here’s an idea for making a desk lamp that uses a magnet-mountable LED light.

The stand is entirely wooden, and the arm is movable so you can adjust the angle.

First, think about what size you want and what kind of structure you’re aiming for, and try drawing a design plan.

Once the plan is ready, figure out the lengths and quantities of wood you’ll need and source the materials.

These days, you can even find small pieces of wood at 100-yen shops, so those might work as well.

One of the joys of woodworking is choosing the finish—whether to go for a natural look with varnish or oil, or paint it your favorite color—so definitely consider a variety of options.

Original T-shirts made with stencil printing

Perfect for summer vacation crafts and DIY! How to make an original T-shirt with stencil printing!
Original T-shirts made with stencil printing

How about making your own T-shirt over summer vacation? We’ll use a technique called stenciling to create an original T-shirt.

You place a cutout of letters or illustrations on the fabric and paint over it with ink or other pigments.

Since you’ll wear the T-shirt, you’ll likely wash it too.

When stenciling on T-shirts or fabric, be sure to use fabric ink that won’t wash out.

While this can be a summer vacation homework project, it can also become a fun summer memory.

You might even make matching T-shirts for the whole family.

There are stencil T-shirt kits available online, so why not give them a try?
