Handmade piggy banks with fun mechanisms! A collection of summer vacation craft ideas that will amaze even adults

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 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.

aquarium piggy bank

[Challenging] The Fish Move! Aquarium Piggy Bank [Woody Clay]

I’ll introduce an idea for making a piggy bank that looks like an aquarium when you rotate a plastic bottle.

First, prepare a 500 ml plastic bottle.

Wrap the bottle with cardstock and then bubble wrap in that order, and use a pen to draw several holes where fish will be visible.

Except for those holes, attach clay around the surface.

Use the clay to create coral, shells, and any decorations you like.

Once the clay dries, remove the plastic bottle, and make a single hole in the bottle that matches the size of one of the clay holes.

This will be the coin slot, which can open and close by rotating the bottle.

Draw fish on the plastic bottle with a permanent marker, and finally seal the bottle’s mouth with a fish made out of clay.

You’re done!

Sparkly plastic-bottle piggy bank

DIY #2 A Must-See for Girls! A Sparkly Piggy Bank Made from a Plastic Bottle

Here’s a craft idea for making a dreamy-cute piggy bank out of a plastic bottle.

First, cut the bottle about 10 cm down from the mouth, and cover the cut edge with masking tape or similar.

Don’t forget to make a slot for inserting coins.

Cut out two round pieces of cardboard to match the size of the bottle’s bottom; make one slightly smaller, then glue it on top of the larger one.

Poke a hole, pass a toothpick wrapped with a rubber band through it, and secure with tape.

Make a hole in the plastic bottle as well, thread a string with beads through the hole, tie it on the inside to secure it.

Hook the rubber band onto the beads, and if the bottom closes firmly, you’re good to go.

Finally, decorate the bottle and the cap with beads and decorative stickers, and you’re done!

Spinning piggy bank

Why not make a fun piggy bank where the coins spin as they go in? It’s a perfect idea for a summer vacation craft.

First, slice a milk carton into rings, press the corners to flatten the center space, and make four “blades” to form a propeller.

Decorate the edges with vinyl tape, and make two large propellers and four small ones in the same way.

Skewer a large propeller on a bamboo stick, then add two small propellers on each side to create a spinning mechanism.

Insert this into a clear tube, make a coin slot in the lid, put the lid on, and you’re done.

A piggy bank with a wagging tail

How to Make a Tail-Wagging Piggy Bank [Paper Clay, Swan, Creative Piggy Bank]

An adorable piggy bank with a gently swaying tail! Start with the tail parts.

Fit a straw onto a bamboo skewer, then wrap wire around the straw so the wire sticks out to the left and right.

Cover the protruding wire with paper clay, shaping one side into a tail and the other into a paddle shape.

The key is to adjust the amount of paper clay so both sides are evenly weighted.

Once the paper clay is completely dry, attach it so the paddle part fits inside the main body made from a milk carton, and shape the exterior with paper clay however you like.

All done!

Walking piggy bank

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

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!

Omikuji piggy bank

[Omikuji Coin Bank] Sakura’s Crafts Room 18: Let’s make it with a milk carton — perfect for a summer vacation independent research (craft) project! DIY Coin Bank from a Milk Carton

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.
