Handmade toy from an empty snack box

[Elementary School Summer Vacation Crafts/Independent Research] Handmade Toys Using Empty Snack Boxes 🌻 #SummerVacationCrafts #IndependentResearch #Crafts #EasyCrafts #PlayAtHome #HandmadeToys #DIY

Make it with an empty snack box! Here’s how to create a pom‑pom shooting game! First, prepare an empty box that once held something like Choco Pie.

Reinforce the back by attaching a wooden stick so the lid can stay open.

Next, glue wooden sticks to the top and bottom of a wooden clip and wrap a rubber band around it.

Attach a plastic bottle cap to one end, and fix the other end to the back of the box.

Finally, stick a few small paper cups inside the box wherever you like, and you’re done.

Set a cotton ball in the bottle cap and launch it with a pop—have fun playing!

Let’s make a super ball

Simple Craft: Let's Make a Super Ball! #MakeASuperBall #ElementarySchoolExperiment #shorts

Did you know you can make a super ball yourself? You’ll need PVA laundry glue, salt, and food coloring or paint.

First, dissolve 40 g of salt in water and add color, then pour the saltwater into the glue and stir with a chopstick.

You’ll see a gooey mass start to form around the chopstick.

Gather it up and blot the moisture with a paper towel, and you’ll have an easy homemade super ball.

Depending on the batch, some bounce very well and others less so, but try adding your favorite colors and make all kinds of super balls!

Infinity Cube made from a milk carton

[Summer Vacation Crafts / Independent Research] Infinite Cube with a Milk Carton #SummerVacationCrafts #IndependentResearch #EasyCrafts #DIY #Craft #KidsActivitiesAtHome #ElementarySchool

The endlessly flippable infinity cube is so much fun, isn’t it? Let’s make one using milk cartons.

First, wash and dry the cartons, then prepare two cartons with the top and bottom cut off.

Cut each one into eight vertical strips to make 16 long, narrow pieces.

Next, use two pieces to make one cube.

There’s a trick to how the cubes are connected, so be careful not to connect them the wrong way.

Once you’ve connected them correctly, stick origami paper on top, and you’re done.

Snow globe made from an empty bottle

[Craft with Empty Bottles] Let’s Make a Snow Globe!! #ElementarySchool #DollarStoreCrafts #shorts

Many people have probably received or bought snow globes as souvenirs or gifts.

Why not try making one with an empty jar? It’s easier than you think, and the result is beautiful and soothing.

All you need is an empty jar, a melamine sponge, liquid laundry starch (or thick laundry glue), small figurines or similar parts, and some glitter.

You can get them cheaply at a 100-yen shop.

First, attach the melamine sponge to the inside of the jar lid, then glue the figurines or other parts onto the sponge.

Put glitter into the jar itself, add laundry starch and water, mix, and screw on the lid—that’s it!

[Laminated] Pressed Flower Bookmark

[Pressed Flowers from the 100-Yen Shop] Daiso’s laminate film! Easy, machine-free lamination for making pressed-flower bookmarks. Tips for creating durable bookmarks included.

Let me introduce how to make a pressed-flower bookmark.

You’ll need business card–sized laminating film, tweezers, scissors, a ruler, and pressed flowers.

First, cut the laminating film in half.

Peel one piece partway open and arrange the pressed flowers as you like on the adhesive side.

Then align it with the adhesive side of the other piece and press them together firmly.

Trim any misaligned edges with scissors to neaten the shape, and you’re done.

You can easily make pressed flowers by sandwiching blooms between cardboard, tissues, and parchment paper, then heating them at 500W for 50 seconds.

Thin flowers work best.

Try making a cute, original bookmark!

Let’s try putting ice in various liquids

[Independent Project] Let's put ice in various liquids!

How about trying to put ice cubes into various liquids? The results can be surprising, so both adults and children can enjoy it together with excitement.

First, prepare several plastic cups and fill each one with a different liquid.

Water, salad oil, milk, and alcohol-water mixtures work well.

Next, drop an ice cube into each cup.

You should see that some ice floats while others sink.

Think together about why that happens.

Also, you might make some discoveries by measuring how fast the ice melts in each liquid.

Let’s make canned space

How to Make a Galaxy Jar [Parent-Child Craft]: How to Make a “Bottled Universe.”

Shall we try making a beautiful, dreamy “bottled cosmos,” a lovely interior decor item that’s popular overseas? You’ll need an empty jar, craft cotton, water-based paint, a brush, and your choice of glitter, star-shaped beads, or sequins to create a space-like vibe.

You can make it with items you already have at home or from a 100-yen shop.

First, pack the cotton firmly into the empty jar.

Since it’s fluffy, it may look full right away, but gradually add a little water and press it down tightly.

Spread 2–3 colors of paint bit by bit around the cotton, add glitter, and you’re done.
