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.

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.

A toy that uses a lid

@n.annlee321

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.
