Water you can grab and play withNEW!

This content explains how to make a mysterious object that looks as transparent as water yet can be held in your hand, using a simple combination of materials.
You’ll use a plastic balloon kit; by putting water inside it, you create a transparent balloon that encloses water.
The method is to apply the plastic balloon to something with a hole—like a five-yen coin—then add water and inflate it.
Because the materials are so simple—just water and a plastic balloon—it may be easy to think of variations, such as changing the color.
Zabuton relayNEW!

Spinning a zabuton above your head while keeping your balance is a classic street-performance-style game.
Because it’s wide, it’s easy to balance on your hand, but getting it to spin smoothly takes some tricks—that’s part of the fun.
Focus on placing your hand right at the center, applying force so the whole cushion spreads outward as it turns, and keeping the angle straight.
As you get used to spinning it, try more advanced moves like tossing it up and catching it.
Underwater Coin Drop GameNEW!

It’s a game where a small cup is placed inside a large jar filled with water, and the goal is to toss coins so they land in the cup.
The key is that the coins don’t travel straight because of water resistance, so you need to read their complex movement.
The shape of the large jar also matters: the longer the distance to the bottom, the more complex and harder to predict the coins’ paths become.
If you play with multiple small cups and make it a rule to land a coin in every one of them, you can also enjoy the tantalizing frustration of being just one cup short—highly recommended.

Lupin the Third Theme (High Quality) – Sound Works
This is a game where you shake and move the water inside a plastic bottle and use that motion to spin the bottle.
Let’s carefully figure out how to make the water move effectively and how that movement transfers to the bottle.
It’s recommended to color the water so the motion is easier to see; watch its position as you move it.
The way you move it will vary depending on the size and shape of the bottle, so it’s also a good idea to try different patterns.
Clothespin scoopingNEW!
@chibiike [Solo Rec That Avoids Crowding] Supervised by a Recreation Caregiver! Easy Indoor DIY Game Video for Seniors: “A Game Where You Thread a Chopstick Through the Hole of a Clothespin and Take It Off”#chibiike
♬ Somebody To Love – from LC
It’s a simple game where you use a stick to scoop up clothespins arranged on the spot.
As you go, figure out how each clothespin is standing and which part to hook to lift it.
The flow—precisely hooking with the stick, pulling up quickly, and instantly deciding the next target—lets you test various skills within a simple setup.
It’s recommended to make results visible, such as timing how long it takes to scoop them up, and aim for higher scores.
Toothpick Balance GameNEW!

This is a game where you enjoy achieving a perfect balance using a bundle of toothpicks in a case.
First, pull the bundle out of the case just a little, then place a single toothpick on top.
From there, the idea is to push the base toothpicks back into the case so that the one on top doesn’t fall.
Sometimes boldly, sometimes delicately—you can enjoy the inner tug-of-war as you strive for the best balance that keeps it from dropping.
The fact that you can play it as long as you have a bundle of toothpicks makes it perfect for killing time.
Alice’s Time LabyrinthNEW!

Board games are often seen as something to play with a group, but their variety also caters well to smaller numbers.
Covering small groups thoroughly—and even enjoyable solo—Alice’s Time Labyrinth is such a board game.
You aim to defeat embodiments of darkness using your hand of cards, and the strategy of how to strengthen your deck is part of the fun.
As you replay the game, think about the smoothest way to power up, and discover the best approach that works for you.
Goo-Paa ExerciseNEW!

This is an exercise where you switch the shapes of your hands and arms in sequence to help train your brain.
The basic hand shapes are a fist and an open hand: extend one arm forward with an open hand, and pull the other arm back with a fist, then alternate.
By changing the hand shapes during these switches, you add a thinking element that activates the brain.
Once you get used to this simple alternation, increasing the variety of hand and arm shapes to make it more complex will lead to even greater brain activation.
Last Dungeon DiceNEW!

This is a solo-play board game where you assess the situation, roll the dice, and aim to clear the challenge.
The story—repelling adventurers as the Demon Lord’s dungeon master and preventing the rescue of the princess—helps you get fully immersed in the game.
Your strategy and your luck are both put to the test: how you plan your moves and which dice results you manage to roll will determine your fate.
And since it’s a game you can play alone, the ability to take your time and carefully construct your approach is a major part of its appeal.
Back catchNEW!

It’s a simple game that still takes some practice: throw a ball up and catch it behind your back.
Start by catching the ball in front of you to learn an easy way to throw and get used to handling the ball.
Once you’re comfortable, move on to catching it behind your back.
Check how far your hands can reach on your back, and try to meet the ball in that position.
Begin with low throws, then gradually throw higher to increase the difficulty.
This progressive approach is recommended.
