Walking piggy bank

How to Make a Walking Piggy Bank Powered by Rubber Bands ♪ [Paper Clay & Craft]
Walking piggy bank

Let’s make a toddling walking piggy bank! The main material is a paper cup.

Cut the paper cup along a line slightly closer to the bottom than the halfway point, then combine the two parts and secure them with tape.

On what will be the bottom side, make four slits and attach a battery wrapped with a rubber band.

Reinforce the slit areas with cellophane tape so the battery won’t come loose—this completes the movement mechanism.

Finally, cover it with another paper cup that has a coin slot cut into its base, add your favorite decorations, and your walking piggy bank is ready!

A piggy bank where coins disappear

[Coin-Disappearing Piggy Bank] Make it with a milk carton! Perfect for a summer vacation independent study (craft)! DIY Coin Bank from a Milk Carton
A piggy bank where coins disappear

A mysterious piggy bank where the coin you put in disappears! The secret behind the disappearing act is a cutting mirror hidden inside the box.

A decorated sheet of construction paper is fitted inside a milk carton, and then another milk carton with a cutting mirror attached at an angle is inserted.

So when you peek through the window, it looks empty even after you put money in.

It’s a clever idea that makes good use of the properties of mirrors.

You can make it with simple materials, so it’s perfect for those “I have to turn this in in a few days…” moments! Give it a try.

Log cabin-style piggy bank

Make it with toothpicks! Log house piggy bank [making]
Log cabin-style piggy bank

This is an idea for making a log-cabin-style piggy bank by lining up toothpicks and gluing them together.

The process isn’t difficult since it mainly involves cutting toothpicks, arranging them, and gluing, but it can be tedious because of the fine work.

Still, the finished log house will be sturdier than expected, so it’s definitely worth making! Creating a blueprint in advance helps you work without hesitation and reduces mistakes, so it’s recommended.

You could also make it using ice cream sticks or disposable chopsticks instead of toothpicks.

Omikuji piggy bank

Here’s an idea for a fortune-slip coin bank made from a milk carton.

Decide the size you want, cut the milk carton, and build the main body of the bank.

Make a coin slot on the top and an opening on the bottom to retrieve the money, then also make holes to insert a bamboo skewer.

Make two holes on opposite sides.

Next, from the remaining milk carton, cut out a ring 4 cm high, then squash it into a cross shape by folding the corners inward toward the center.

Staple it so it holds its shape, and fold the four ends about 1 cm in the same direction.

Thread a bamboo skewer through the center, install it inside the main body, then attach the fortune-slip component made from cardboard to the outside end of the skewer—and you’re done! If you want to decorate the body, do that before inserting the bamboo skewer.

Sumikko Gurashi piggy bank

[Perfect for a Summer Vacation Project!] How to Make a Piggy Bank (Sumikko Gurashi)
Sumikko Gurashi piggy bank

I’ll introduce how to make a Sumikko Gurashi piggy bank out of origami.

Prepare two sheets of origami paper and one small sheet, then let’s get started.

Use the small origami paper to make the 5-yen coin part.

Fold the corners toward the center, then fold the surrounding corners as well.

It will form the shape of a 5-yen coin, so draw the details with a felt-tip pen.

For the base piggy bank, fold the origami toward the center to create creases.

Following the creases, tuck the paper inward to form a square box.

Make two identical boxes; on one of them, attach the 5-yen coin and draw the face.

The key point is to change the color of the origami depending on the character.
