Craft ideas made with origami and a shredder

The shredder was a fun crafting tool ☺️🙌 This is a piece my son made 😁 More details in the comments →#tiktok classroomLife with children#StayHomeTime

Let’s use the shredding function that cuts paper into fine strips to create various shapes.

We’ll use a hand-crank shredder, and by controlling where you stop shredding and other small tricks, you can make different parts and combine them.

Food motifs are an easy example: if you insert long, thin strips sideways and shred them even finer, they can look like a coating or breading; roll up long, thin strips and they’ll resemble shredded cabbage.

By layering parts and experimenting with how you bend them, you can also add a sense of three-dimensionality.

Think carefully about how to reproduce what you want to make.

Simple salt sand art

This is about layering different colors of salt in a glass to create a picture-like, beautiful look.

Start by making colors that match what you want to create: mix paint into the salt to prepare it.

Once your colored salt is ready, simply layer it into the glass.

It’s best to pay attention to the boundaries between colors and avoid overmixing.

After filling the glass, press the layers to compact them—you can aim for more complex shapes this way.

Try various patterns to see what you can achieve.

Paper cup Tyrannosaurus

[Summer Vacation Craft] Using Only Paper Cups! Easier T. rex (Tyrannosaurus) Project [Independent Study] Make It in One Day! Upcycled Craft [A Must-See for Moms and Dads]

This activity involves combining paper cups to create a three-dimensional, dynamic Tyrannosaurus.

The key is how you connect the cups: by trimming the edges and adding slits, you can set firm angles.

Build it by linking the cups from the head to the tail, then attach separately made legs and arms at the end to finish.

Try different variations, such as using cups of the same color for a cohesive look or mixing different colors for a colorful effect.

Making a marble run with an ice box

Summer is the season that makes you crave ice cream, and as you eat it, you might find the boxes piling up.

This idea uses those leftover ice cream boxes to make a marble run.

Use a large box, like a milk carton, as the base, and attach slopes made by cutting the ice cream boxes around it.

Adjust the angles and heights carefully, keeping in mind the strength needed so it won’t break when the marbles hit.

Using ice cream sticks to reinforce it is also recommended—they’ll make the whole thing sturdier and give it a cohesive look.

Roll-and-drop game made with straws

@n.annlee321

Roll, roll... ☺️#tiktok classroomLife with children#Summer VacationSummer Vacation Craft

♬ Athletic Meet “Heaven and Hell” (No Introduction) – Shinonome

Here’s a fun-to-make, fun-to-play marble run you can build with straws.

Gather tapioca (boba) straws, beads, masking tape, and scissors, and let’s get started.

Cut the tip of a tapioca straw at an angle, then tape it to a wall with masking tape, adjusting the angle as you go.

Add guards at the ends of the straws so the rolling beads don’t fall out.

The key is to tweak the angles so the beads roll smoothly.

Once it’s finished, try rolling some beads and play! It could also be fun to turn this into a little science project—prepare beads of different sizes and time how many seconds each one takes to roll through.

♬ Relaxing, cute everyday BGM – Avi

Do you have leftover cold packs from buying cakes and other treats sitting in your freezer? Here’s a deodorizing gel pot you can make with those cold packs—perfect as a summer science or craft project for upper elementary students.

Get your materials ready: cold packs, beads, a plastic container, an empty jar, colored markers, a bowl, water, and a stirring stick.

Squeeze the contents of the cold pack into the bowl, add water, and stir until it becomes a gel.

Color the bottom of the plastic container, then add the gelled cold pack and mix to tint it.

Spoon the mixture into the empty jar, add beads or other decorations, and you’re done.

Well-spinning paper cup top

[Playable Craft] How to Make a Simple, Well-Spinning Top (Paper Cup & Plastic Bottle Cap) [Easy Crafting with Recycled Materials] Fun at Home

This is a spinning top made with a paper cup that spins well and is fun to watch because of its colorful look.

All you need are a paper cup and two plastic bottle caps.

First, cut slits into the paper cup and spread them out like propeller blades, then attach an axle made by combining the two caps.

That’s enough to complete the basic shape, but it’s recommended to decorate the “propellers” with an eye toward how it will look while spinning.

The impression changes depending on whether you spread the propellers before decorating or decorate first and then cut the slits, so try out various patterns.
