gachapon

[Easy] How to Make a Gachapon Machine: Cardboard Gacha/Gashapon
gachapon

Gachapon machines you see at supermarkets and family restaurants.

Many children probably gaze at the rows of machines with sparkling eyes.

So, let’s try making a gachapon out of cardboard.

Cut the cardboard to the sizes needed for the machine and assemble it using a hot glue gun.

You can get a hot glue gun at a 100-yen shop, and it has stronger adhesive power than regular glue, so it’s recommended.

Not only is the building process fun, but it’s a project you can enjoy even after it’s finished.

These days, the contents of gachapon can be quite unusual, ranging from region-exclusive collaboration items to cooking recipes.

Be sure to get creative with what you put inside the capsules, too.

In recent years, cardboard has been gaining attention as a material that can be used for disaster-relief beds, toilets, partitions, and more.

Cardboard is lightweight, and depending on how it’s assembled, its strength can be increased.

Because cardboard is also a familiar material for crafts, consider using it for summer break independent research or craft projects.

A cardboard chair that can be made simply by assembling pieces cut and notched from cardboard looks cool, is highly functional, and is a project you can actually use after making it.

Conveyor Piggy Bank

Conveyor Piggy Bank

A conveyor-belt coin bank that swallows coins one after another! Make the main body of the bank from a milk carton, and install a mechanism inside using items like bamboo skewers, thick paper, plastic bottle caps, and rubber bands.

Then, combine the mechanism with a belt, and you’ll have a coin bank where turning a lever moves the belt.

Adding a face around the coin intake gives it a comical look.

If the belt’s joint is misaligned, it won’t run smoothly, so be sure to attach it straight when connecting the ends.
