Hands-on science projects elementary school boys will love! Ideas you can make with everyday materials (41–50)
disposable chopstick coaster
Introducing a chopstick coaster that lets you feel the warmth of wood.
Gather disposable chopsticks, glue, sanding sealer, varnish, and a brush, and let’s get started.
Glue chopsticks around the base board.
If you score the chopsticks with a utility knife before splitting them, they’ll break cleanly.
Lightly sand the tips to round them off.
Continue gluing the chopsticks from the outside toward the inside.
Adjust the size of the chopsticks as you go, fitting them while slightly changing the angle.
Brush on varnish and let it dry, and you’re done.
Give it a try!

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.
64-shot cardboard chopstick rubber band gun
A must-see for anyone who wants to push the limits of rubber band gun rapid fire! With this cardboard-based gun, you can fire an incredible 64 shots in a row! All you need is cardboard, a plastic bottle, chopsticks, rubber bands, kite string, plus a motor, batteries, and vinyl wire.
It’s a proper build with a built-in motor, so the difficulty is high—but that just makes the satisfaction of completing it even greater! Perfect for a summer vacation project or a stay-at-home activity during a long break—give it a try when you have time to take it slow.
Just be prepared: picking up all the rubber bands after 64 shots might be a bit of a challenge…
DIY speakers
How about making a speaker that you can plug your smartphone or portable music player into? Building a speaker might sound difficult, but to put it simply, all you need to do is make a hole for your phone—it’s that easy! Use an empty cylindrical container, like one from a snack.
Cut a hole with a utility knife big enough to fit your phone, and loosely stuff some toilet paper inside—then you’re done.
You can add a base so it stands firmly, and decorate the tube to create a cool, one-of-a-kind speaker!
How to Make an Easy Guitar
A simple guitar you can make with paper cups lets you easily live out the dream of strumming a ringing guitar.
First, glue the bottoms of two paper cups together.
Then stack another paper cup on each side with slits cut into them, and attach rubber bands into those slits—done.
The key here is the length of the rubber bands.
By choosing which slit to anchor them in and lining up rubber bands of different lengths, you can create differences in sound just like a real guitar.
Think about what kind of sound will make it feel cool, and fine-tune it into your ideal guitar.
Handmade maracas
This craft is inspired by maracas made with paper cups that produce a cheerful rattling sound when lightly shaken.
The steps are simple: put beads or finely cut pieces of straw into a paper cup, then cover it with another paper cup as a lid.
What you put inside is important—consider how different fillings change the sound as you make it.
Decorating the outside is also a key point; aim for fun decorations that match the light, lively sound of the maracas.
Handmade telescope
Bring distant things close enough to feel like you can reach out and touch them! Let’s try making a cool-looking telescope.
You’ll use two magnifying glasses, a pair of reading glasses, and a cylindrical container like the kind used for snacks.
The basic method is: attach the two magnifying glasses together and mount them on the viewing end of the tube, then take a single lens from the reading glasses and attach it to the far end.
That’s all it takes to make a real telescope.
Both the magnifying glasses and the reading glasses can be the inexpensive kinds sold at 100-yen shops.
