Crafts to learn how things work (41–50)
Dinosaur Snow Globe

Many children love dinosaurs, don’t they? Some probably have lots of dinosaur merchandise, too.
So let’s make a summer vacation project using dinosaurs: a snow globe in a glass container filled with liquid laundry starch (or school glue) and purified water.
Use a hot glue gun to attach a dinosaur figurine to the inside of the glass lid.
Be careful when using the glue gun, as it gets very hot.
Pour the laundry starch (or glue) and purified water into the container, then tint it with paint in your favorite color.
If you add glitter, you’ll get a sparkly, authentic-looking snow globe.
Close the lid and turn it upside down, and you’ll have a beautiful snow globe with a dinosaur inside.

Insect interior

This is an idea for turning insect specimens into stylish interior decor.
When you think of specimens, you might picture them in a box, but what we’re introducing here uses a jar.
You’ll need a jar with a cork lid, an acrylic sheet, and an insect specimen.
The process is simple: first, cut the acrylic sheet to a size that fits inside the jar.
Next, make a slit in the cork lid, insert the cut acrylic sheet, and secure it with adhesive.
Finally, attach the insect specimen to the acrylic sheet and close the lid to finish.
Using a clear acrylic sheet makes it look as if the insect is floating inside the jar, creating a very chic look.
Sea memo stand

Some families may go swimming at the beach during summer vacation, right? When we think of the hot summer, many children surely picture the sea.
So why not make a memo stand using resin with an ocean theme? Prepare parts to embed in the resin, such as seashells, sea creatures, and clear or blue stones.
Of course, it’s also nice to include shells you picked up at the beach.
Place your favorite parts and the memo stand into a container, then pour in the resin.
After that, leave it undisturbed for the specified time.
At this stage, the key is to prevent dust and debris from getting in—for example, by placing the piece in a box.
If you include seashells you collected at the beach, you can create a lovely piece that captures your summer memories.
stone art

Let’s make stone art using materials close at hand, like those from rivers and parks.
Start by collecting stones and twigs.
Choosing stones without sharp edges will help you create cute pieces.
Also, selecting twigs with branches is a key tip for making a lovely work.
Arrange the stones and twigs you found on a frame or cork board, which you can also buy at a 100-yen shop.
As children think, design, and create on their own, it boosts their imagination.
You can paint the pieces, and it’s also nice to add pinecones, leaves, and other items besides stones and twigs.
Let’s make a bamboo lantern

Here’s how to make a bamboo lantern that looks beautiful when it glows at night.
Use a saw to cut the bamboo.
Make slits in the cut bamboo, then gently tap from above with a hammer to create openings where the light will shine through.
The key is to tap with the hammer without using too much force.
Drill holes to create several small windows for the light to leak out.
Wrap yarn around the top and bottom of the bamboo tube, using double-sided tape to secure it.
Place an LED light inside, switch it on, and let it shine.
It emits a soft glow that gives off a traditional Japanese ambiance.
How to make a paper popper

Here’s how to make a simple paper pop gun using a plastic wrap core.
First, roll up some paper to make a small ball about 1 cm in diameter.
Cut a balloon around the middle and attach it to the end of the wrap core.
Secure it with a rubber band so it doesn’t come off, and you’re done! Put the paper ball inside, pull the balloon back, and launch the paper ball you made.
You can also decorate the gun however you like or use cardboard to give it a cool gun shape.
Have fun with your own original ideas!

Let me introduce the Chopstick Chomping Crocodile—its moving face is super fun! Get some chopsticks, rubber bands, and origami, and let’s make it.
First, split two pairs of chopsticks.
Align each pair lengthwise and secure them with rubber bands.
Once you have two secured sticks, attach them together top and bottom with rubber bands so they can open and close.
Finally, glue or tape a face and mouth to the tips of the chopsticks, and you’re done.
Give it a try for some chomp-chomp fun! Since the method is simple, it could also be fun to swap the crocodile for another animal.
