How to make a chopstick tree

[Christmas Craft] Easy with chopsticks and yarn! How to make a Chopstick Tree [Ashitaba Channel]

Here’s how to make a chopstick tree that lets you enjoy a cozy nighttime atmosphere when you light it up.

Prepare chopsticks, yarn, glue, and decorations like beads, then get started.

First, build the tree’s frame with chopsticks.

Wrap yarn evenly around the base.

For a summery feel, you could use colors like light blue or pale green.

Once you decorate it with summer-themed items such as watermelon or fish-shaped wind chimes, your chopstick tree is complete.

It’s sure to captivate elementary school kids, too.

Try changing the seasonal theme as you make it—you might discover something new each time.

Paper slingshot made from origami and chopstick sleeves

Paper Pachinko: An Easy Way to Make One with Origami and Chopsticks — Kids Can Make It Too

A slingshot is a Y-shaped gadget used to launch pebbles or paper far into the distance.

At first glance it might seem like just a toy, but similar hunting tools have existed all over the world since ancient times.

The need to propel objects far is what gave rise to that shape.

Let’s try making such a slingshot using chopsticks.

The key to building a sturdy slingshot is reinforcing the space between the Y-shape with a toothpick.

There aren’t any particularly difficult steps, so even younger elementary school children should be able to make it.

You can switch up what you launch—paper, stones, clay, slime, and more—and turn it into a science project-style exploration.

“Wankoppu,” which sounds like a dog’s bark

Real!? A cup that makes a sound like a dog barking: 'Wancup' #crafts #handmadeToys #easyCrafts

This is a craft project: a dog mascot made from a paper cup that emits a sound like a real dog when you pull a chopstick attached to its tail.

The key is how to attach the pipe cleaner tail.

Attach a clip to the end of the pipe cleaner, thread it through a hole made in the paper cup, and secure it so that impacts resonate through the cup.

Once this part is complete, decorate the rest using a small paper cup, origami paper, and so on to create the dog’s appearance.

Then, by pinching the pipe cleaner in the gap between the chopsticks and pulling, the pipe cleaner’s vibrations are transmitted to the paper cup, producing a sound that resembles a dog’s bark.

How to make a paper-cup kendama

[Craft Play 073] How to Make a Paper Cup Kendama

This is a paper-cup kendama made with a paper cup and plastic bottle caps.

First, poke a hole in the center of the bottom of the paper cup and thread a 60 cm piece of yarn through it.

Be careful not to hurt yourself when making the hole.

Tie a knot at the end of the yarn so it won’t slip out, and secure it to the outside bottom with cloth tape.

Tie a knot in the other end of the yarn as well, place it between two plastic bottle caps facing each other, and fasten them together with cloth tape.

That’s all it takes to complete the main body! After that, customize it with stickers or markers in any design you like.

It’s great because even kids who struggle with a real kendama can have fun and play together!

Paper cup cracker

[Paper Cup Craft] How to Make a Party Popper

Party poppers are a must-have at celebrations—the loud pop and the confetti bursting into the air really bring the fun.

This project shows how to make a popper that bursts confetti using a paper cup.

First, make a hole in the bottom of the paper cup and insert a rubber band that’s been tied to a toothpick, anchoring it to the bottom and securing it with tape so it catches firmly.

Wrap one end of the rubber band with folded aluminum foil to create a piece that can strike the bottom of the cup—this completes the base.

Next, put confetti or finely cut pieces of straw inside.

When you pull and release the rubber band to deliver an impact, the contents shoot out like a party popper.

As you build it, experiment to see how the confetti scatters and rises.

Paper cup fireworks

[Online Kindergarten] Paper Cup Fireworks: Parent-Child Craft at Home <Official from Kodomo Challenge>

Fireworks burst out of a paper cup! How about enjoying a bright, summery craft? First, prepare some copy paper and draw any patterns you like.

Crayons or pens with vivid colors are recommended.

Next, cut the paper in half, accordion-fold each piece, then fold them in half again.

Make a hole in the center of the bottom of a paper cup and insert a chopstick.

Finally, attach the accordion-folded pieces to both sides of the chopstick, and fix their ends to both sides of the cup to finish.

You’ll love the satisfying pop as the fireworks open! It’s easy to make, so give it a try.

A toy that uses a lid

Usable... lid!!!TranslationHaagen-Dazs hand-made toy 100-yen shop DIY#KindergartenMom#Kindergartentranslation#ElementarySchoolMom

♬ Double Double FIGHT! – Intro ver. – CANDY TUNE

Haagen-Dazs is hugely popular for its ice cream.

How about turning the lid—something you’d usually throw away—into a cute science project? In this video, they put sequins inside to make a shaker-style lid, and they also poke in pipe-cleaner flowers to create a little trinket box.

With a bit of creativity, you can use lids from other ice creams to make all kinds of toys.

For example, how about making menko (slap-battle cards)? The weight and thickness seem just right.

With bottle-milk caps, you could make character medals.

If you coat them with gold or silver paper, you’ll get super cool-looking medals.
