Why not try making a herbarium, a popular interior decoration? Prepare a container, your favorite flowers and beads, and baby oil.

First, place the flowers and beads into the container, being careful not to overfill it.

Also, if anything tends to float when put in liquid, soak it in the liquid beforehand.

Once you’ve added all the parts, slowly pour in the baby oil, close the container lid, and it’s done.

You can also focus on choosing a stylish container and decorate it with stickers or washi tape to make it extra cute.

Plastic bottles are often used as materials for crafts.

So this time, how about making musical instruments with plastic bottles? Empty bottles can become drums, flutes, or maracas… With a bit of creativity, they can transform into instruments you can actually play! Bottle caps can also be turned into instruments by combining them with other materials, so don’t throw them away—save them.

It’s also a great idea to keep notes on how the sound changes depending on where you make holes and what you put inside.

Let’s make a cute bee keychain.

First, stick double-sided tape all over a chenille stem and shape it into a rectangle.

Wrap a yellow chenille stem around it, then wrap a brown one to create the stripes.

Make wings from a clear file sheet, attach them to the body with the brown chenille stem, and add eyes.

Finally, attach the keychain hardware and you’re done! With a bit of creativity, you can make all kinds of insects and animals, so try making your own original keychains.

Looks just like the real thing! Let’s handcraft some happy noodles.

Flatten a cotton ball made from yellow embroidery thread to form a lump of noodles.

Also, wrap another embroidery thread around chopsticks and soak it in water mixed with liquid starch.

Once it dries and you remove it, it will turn into curly noodles, so make some of those too.

Use a small paper cup as the container and attach a package label you designed with a design app.

Put in the noodles and a packet of toppings, then stick on the lid to finish! You might even be able to use it as a keychain if you add some parts.

It’s like a jewel! Let me show you how to make cute, jiggly soap.

You’ll need liquid hand soap, gelatin, hot water, and food coloring.

Dissolve the gelatin in hot water, then mix in the liquid hand soap.

The trick is to stir slowly so it doesn’t foam.

Add food coloring, pour into a flat container, and chill in the refrigerator for 1–2 hours.

Then just cut it into your favorite shapes and you’re done! It looks adorable and might make handwashing more fun.

Just be careful to prevent small children from accidentally swallowing it.

Sparkling Kaleidoscope

Sparkling Kaleidoscope: Perfect for summer vacation crafts and independent research!
Sparkling Kaleidoscope

If you’re unsure what to make for your summer vacation craft project, why not try a sparkling kaleidoscope? You can make this kaleidoscope with recycled materials and items from the 100-yen shop.

Cut a hard plastic case and form it into a triangular prism, then place beads in the bottom and secure them.

On the opposite end, attach a piece of black construction paper with a peephole.

Glue a milk carton—lined on the inside with black construction paper—around the triangular prism, and decorate it as you like to finish.

While kaleidoscopes typically use mirrors, in this idea the hard plastic case serves that role.
