Marble Kaleidoscope

Marble Kaleidoscope

A marble kaleidoscope that’s perfect for at-home crafting time or independent study projects.

It’s great because you can make it easily with everyday items like marbles and candy containers! First, take acrylic mirrors (you can get them at 100-yen shops), cut them into strips, and combine them to form a triangular tube.

Next, make a round hole in the bottom of a candy container, insert a marble and then the mirror tube, and close it with a lid that you’ve pre-punched—done! Kaleidoscopes may seem hard to make by hand, but you can actually put one together easily with surprisingly simple materials.

Add your favorite decorations to create a kaleidoscope with your own original design—how lovely!

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.

Here’s an idea for making a bag using bag hardware from a 100-yen shop, plant pot mesh, and yarn in your favorite color and material.

First, cut the plant pot mesh to match the size of the bag hardware, then crochet or stitch the yarn onto the mesh.

Once you’ve finished attaching the yarn, sew the mesh and the bag hardware together.

Finally, add the handles and your favorite decorations to complete the bag.

With this method as a reference, it seems like you could create all kinds of items depending on your ideas!

Marble run made from cardboard

Cardboard Craft: Marble Run — Childcare Tips Useful for Practicum and Training
Marble run made from cardboard

Let’s try making a cool marble run using cardboard.

Prepare a rectangular piece of cardboard that isn’t too thick, and cut off one section on the large face and one section on the narrowest side.

Then, using the pieces you removed and other bits of cardboard, build the pathways for the marble to roll along and attach them to the base cardboard.

Instead of connecting every path all the way through, it’s also fun to leave gaps here and there so the marble drops down to the next level and continues.

Be sure to set up the goal area so the marble stops securely and doesn’t roll out after reaching the finish.
