For upper-grade boys! Simple yet awesome craft project [Don’t call it lazy]

I want to make something for my summer break craft project that makes people say “Wow!” but I’d like to avoid anything too difficult.

Great news for upper-elementary school boys! In this article, we introduce intriguing craft projects with clever mechanisms you can build using everyday materials.

Even creations that look complex—like a fountain where water seems to flow upward or a spinning top that floats in midair—are actually surprisingly easy to make.

Once you finish, you can submit your project with an explanation of how it works and use it as a science project, too.

Go ahead and try these fun crafts that apply principles of physics!

Easy-to-make moving toy crafts (11–20)

You can even make a cool toy car using disposable chopsticks! It’s sure to boost the creative spirit of any car-loving elementary school kid.

It’s also highly recommended as a summer vacation craft project, so give it a try.

Combine cut pieces of chopsticks to build a three-dimensional mini car.

You can also attach wheels so it can actually roll! Since the material is chopsticks, it transforms into a toy car with a warm, handmade feel.

You can also have fun painting it in your favorite colors.

Cardboard garbage collection truck

[Cardboard Craft] Even the pros are amazed! Elementary school students recreate garbage trucks out of cardboard! Various refuse collection vehicles reproduced, including models by ShinMaywa Industries, Fuji Vehicle, and Morita Econos No. 197

Let me introduce cardboard garbage collection trucks.

There are different types of garbage trucks, and their movements and installed parts vary.

All of the trucks being introduced are made using cardboard.

By paying attention to details—such as changing the shape of the emergency stop switch section, recreating the tail lamps with plastic sheets, and writing the manufacturer’s name—you can complete a garbage truck that looks just like the real thing.

Understanding the movements and features of each type of garbage truck also makes it easier to imagine the materials you’ll need to prepare.

Be sure to try making a garbage truck in your own style.

Cool rubber band gun

[Rubber Band Gun] How to Make the Latest, Super Cool Pistol! [Easy Summer Vacation Craft]
Cool rubber band gun

Let me introduce a strong and cool rubber band gun.

Prepare 17 bendable straws, a clothespin, tape, and scissors, and let’s make it.

Take two straws and tape their bendable sections together to secure them.

Attach one clothespin to the gap of the joined straws to create the base.

When bundling straws, secure them tightly so the stacked pieces don’t shift.

Stack eight straws by grouping them in sets of four, extend the bendable sections, and build the structure.

When attaching parts together, make sure the straws are firmly fixed so they don’t slip.

Once it’s finished, hook on a rubber band and give it a try!

Handmade handheld fan

[Summer Vacation Craft] How to Make a Handheld Fan Using Recycled Materials — Great for Elementary School Science Projects
Handmade handheld fan

Let’s handcraft a handy fan whose propeller spins vigorously when you pull a string! The materials are toilet paper rolls and thick paper, kite string, a straw, ice cream sticks, a bamboo skewer, and beads.

Combine two ice cream sticks with a bamboo skewer to create the base of the propeller, then attach it—together with a circular piece cut from thick paper—to a pillar made by joining two toilet paper rolls.

Next, tie the kite string to the bamboo skewer and add the straw and beads, then attach cellophane cut into a fan shape to the ice cream stick section to finish.

smart ball

[Summer Vacation Craft] A “Smart Ball” you can make with 100-yen shop items—perfect for your child’s summer homework or independent research project!

Smart Ball is a playful craft that lets you build your very own game while getting excited about the motion of a rolling marble.

Cut lumber to fit a perforated board to create a frame.

Add an incline beneath the board so the marble rolls more easily.

For the launcher, use nails and rubber bands to make a pull-and-release mechanism that shoots the marble.

Attach a plastic sheet on top of the board to enhance the sound and feel as the marble rolls.

Place small pegs called dowels to add unpredictability to the marble’s path.

With creative targets and decorations, you’ll have a one-of-a-kind original Smart Ball game.

It’s a fun way to nurture creativity and observation skills as you play.
