Jellyfish crafts that are great for preschool activities! You can even play pretend aquarium with them.

Have you ever seen jellyfish at an aquarium or in the ocean?

Jellyfish can grow to about 30 centimeters in diameter, and most of their bodies are made of water.

This time, we’d like to introduce a fun jellyfish craft inspired by this popular sea creature!

It’s designed for ages 0 to 5, with activities suitable for each age.

It will stimulate children’s motivation and help them engage enthusiastically in the crafting process.

Once the crafts are finished, it would be great for teachers and children to play “aquarium pretend” together.

Be sure to make these cute jellyfish with the children!

Ages 5+ Vinyl Jellyfish Advanced Edition

[Kids Craft] A Giant Plastic Jellyfish You Can Make Together with Your Child
Ages 5+ Vinyl Jellyfish Advanced Edition

A craft jellyfish that makes use of the soft look of plastic bags—creating a round shape and then deciding how to decorate it is the key.

Inflate a plastic bag with air, tie off the end to make it round for the body, and attach legs using plastic string or similar materials.

Adjust the length and number of legs to match the size of the bag, aiming for a more dynamic effect.

Incorporating ribbon for the leg parts or placing origami or decorations inside the bag will make the jellyfish more colorful and festive, so that’s recommended as well.

A plastic-bag jellyfish you can make using only familiar materials like plastic bags and origami looks impressively realistic and is highly recommended.

There are many steps that even small children can enjoy, such as tearing the origami by hand and putting the pieces inside, so it’s great as a craft to do at home.

However, since you’ll need to make many fine cuts in the plastic bag to create the jellyfish’s tentacles, an adult should assist depending on the child’s age.

By changing the color of the origami, you can make as many variations as you like, so be sure to try different combinations!

One of the biggest charms of jellyfish in the ocean is how they sparkle as they catch the light from outside.

Focusing on that shimmering quality, let’s make jellyfish that are transparent yet colorful.

For the main body, use a cup like those for pudding or gelatin.

First, attach the tentacle parts made from long, thin strips of colored cellophane or ribbon.

Then, wrap the cup with colored cellophane or mesh to complete the overall shape.

Pay attention to the color balance between the tentacles and the body, and to details like the facial features, to create your own unique jellyfish.

A jellyfish sun catcher made from paper plates

A sun catcher made with paper plates, featuring a transparent look using translucent origami called transparent paper, is especially striking.

First, cut the paper plate into a jellyfish shape, hollowing out the center to create a frame.

Next, attach white transparent paper over the cut-out area, then layer finely cut pieces of colored transparent paper on top.

If you layer too many pieces, the light will be blocked, so adjusting how many you stick on is important.

Finally, attach plastic cord or ribbon tape as the tentacle parts, and you’re done.

Think carefully about the color balance and create your own colorful jellyfish.

Jellyfish made from a plastic bottle

PET Bottle Craft: Make a One-of-a-Kind Jellyfish!

It’s an enchanting aquarium that looks as if a tiny jellyfish is floating inside a plastic bottle.

The jellyfish is made by tying a small amount of water inside a plastic bag; by tearing the excess part well, you create tentacle-like strands that also give it a soft, flowing look.

Color the water in the bottle with paint, and later add color with an emphasis on transparency so the jellyfish remains clearly visible.

Finally, place the jellyfish in the bottle and screw on the cap to complete it.

Tilt the bottle up and down to see the jellyfish move.

Try different variations for the jellyfish’s construction and the color of the water to make the jellyfish look even more beautiful.

Here’s a slightly special idea using a small LED light.

Wrap aurora film with stiff tulle and tie off the bottom to make a shape like a teru-teru bozu (a little weather charm).

Slip in a battery with a lit LED bulb, then add decorative threads to represent jellyfish tentacles and attach a strap fitting—that’s it.

A softly glowing jellyfish strap that sways gently in pale colors is absolutely adorable.

Choose whatever light color you like.

Cute jellyfish made with origami

A jellyfish that conveys a sense of cuteness and softness through origami—the three-dimensional feel created by its complex, extending tentacles is also striking.

Fold the paper into a small square by layering the origami, then shape the overlapped sections into thin tentacles.

As you extend the tentacles, use scissors to finely trim the pointed parts; the slender legs enhance the overall three-dimensional effect even more.

Pay attention to the balance of overall color and expression, and aim for a jellyfish that’s even cuter than you first imagined.
