Crafts you can play with

In this Reiwa era, where digital devices have surrounded us since the day we were born, it’s nice to enjoy some analog play from time to time.
So here’s a summer craft you can make and play with right away: the “Wobbly Tree.” Glue a branching tree onto half of a toy capsule.
Hang rubber bands from the branches one by one, and the person who knocks the tree over loses.
If you substitute the toy capsule base with something else, you can make an even bigger tree.
There are also videos introducing other playable crafts, so if you’re interested, be sure to check them out.

A study on easy ice cream you can make in one minute

Have fun with it! Here’s an idea for a simple ice cream experiment you can make in just one minute.
Not many people have actually made ice cream themselves.
How about trying a fun and easy experiment where you can also enjoy delicious ice cream? All you need is milk, sugar, ice, salt, and resealable bags.
The steps are simple and easy to follow, so kids will likely jump right in! And since this is for learning, don’t forget to keep records of what you do!
Magic hand

A magic hand is a device where you use a mechanism to move a hand motif that’s larger than a real hand.
The unique mechanism gives it a slightly awkward motion, which is fun to watch on its own.
To make one, cut construction paper into the shape of a hand, leave openings at the finger joints and apply double-sided tape, then create the “bones” with short pieces of straw.
After that, thread string through the straws and you’re done—when you pull the strings, the fingers curl at the joints.
To make it easy to tell which string controls which finger, it’s recommended to use different-colored straws and match the color at the end of each string to the straw it runs through.
Melon cream soda

Melon cream soda is also appealing for its vibrant appearance—the green color topped with ice gives a refreshing feel, doesn’t it? This is about trying to recreate that beautiful, summery look of melon soda.
The steps are simple: put jelly clay into a plastic cup, insert a straw, and place a scoop of white clay “ice cream” on top.
Combine elements like jewel stones and glitter to make the most of the light and finish it with a sparkling look.
The closer it looks to the real thing, the more you might feel disappointed when you remember you can’t actually drink it.
I wonder what color it will be?

If it’s a fun experiment that feels like an extension of play, everyone will be eager to try it, right? This one can be enjoyed like playing with colored water using just paint, water, and a plastic bottle.
First, fill the plastic bottle with water and dab a little paint on the inside of the cap.
Close the cap tightly and give it a vigorous shake! The plain water instantly turns into colored water.
Try putting two or three colors of paint on the underside of the cap and predict, “What color will it make when they mix?” You might even create a color with no name!
A kaleidoscope like a jewelry box

When you think about making a kaleidoscope, it’s easy to imagine it taking a lot of time and being difficult, right? But this method is a brilliant idea you can do right away with things you already have at home.
Make a hole in the lid of an empty cylindrical snack container to let light in.
Instead of just making a round hole, try a flower shape or something similar to make it even prettier.
Stick some clear tape over the hole and color it with permanent markers from the top.
Wrap the tube with black duct tape, and attach bubble wrap to the end opposite the lid.
If you color the bubble wrap too, you’ll have a colorful and fun kaleidoscope ready to enjoy!
Origami diary

Summer vacation is exciting, but homework is a bit… you know.
If you think of it as something you’re being forced to do, homework can feel endlessly painful and boring.
So why not make it fun? How about turning the drawing part of your summer diary into origami to give it an original touch? Even lower graders could handle this.
If you went fishing, make fish out of origami; if you went to a fireworks festival, try making fireworks with patterned chiyogami.
You’d be surprised how many memories can be recreated with origami! Creating a big ocean scene across a two-page spread would also be really impressive.
If you rush, it stops being fun, so give yourself plenty of time to make it.
