Here’s an idea for making a mysterious bottle that’s fun to display.

The steps are very simple.

First, prepare a bottle in your preferred size and fill it with baby oil, water colored with food dye, and some glitter or holographic flakes.

Then seal the bottle, and it’s done.

It’s fascinating that the oil and water won’t mix, even if you shake it vigorously or tilt it.

Try working on it while thinking, “Why does that happen?” It can also be fun to make bottles in a variety of colors.

gemstone soap

Summer Independent Research: How to Make Gemstone-Like Soaps [Recommended for Girls] [Research]

In recent years, more and more shops have started carrying gemstone soaps.

Some of you might even be using them already.

These beautiful gemstone soaps can actually be made at home.

First, finely cut a colorless, transparent soap base and heat it.

Once it becomes liquid, divide it into several plastic cups.

Next, add essential oils to each cup to give them color and fragrance.

Finally, pour the colored liquids into a single cup to finish.

The appearance changes depending on the order and amount you pour, so try making different variations.

They’re perfect not only for holding books and notebooks, but also as cute interior decorations.

aroma stone

Aroma Stone ♡ Easy 100-yen DIY +* How to Make +* Coloring +* Painting +* Plaster +* How to Make an Aroma Stone +*

I’ll show you how to make aroma stones that are soothingly fragrant and cute to look at.

You’ll need plaster, a silicone mold, watercolor paint, and aroma oil.

First, add 15 g of water to 50 g of plaster and mix well.

Pour the mixture slowly into the mold, then lift and drop the mold lightly several times to release any air bubbles.

Once it’s dry, it’s done.

If you want color, mix watercolor paint into the water beforehand.

You can also paint the stone after it has hardened.

Apply the aroma oil to the back of the finished stone and let it soak in.

Let’s make unbreakable soap bubbles!

[Chokotto⚙Lab] Unbreakable Soap Bubbles

Here’s an introduction to “Let’s make unbreakable bubbles!” Prepare gloves, a bubble-blowing wand, a small plastic bottle, water, dish soap, glycerin, a plastic spoon, and paper towels.

Once you’re ready, pour water and dish soap into a container and mix well with the spoon, then add glycerin and mix thoroughly again.

Dip the green wand into the solution to form a film, and once the film appears, move your arm from bottom to top to create bubbles.

Be careful not to get the solution in your eyes.

Also, when mixing the solution, the key is to stir slowly and thoroughly.

You can substitute gum syrup or liquid laundry starch for glycerin, so try creating unbreakable bubbles with your own custom formula.

rubbing dyeing

Easier than 'tataki-zome' with morning glories: 'suri-zome' (rubbing dye) method that won’t fail — use a spoon, beautiful results — perfect for summer vacation crafts and midsummer greeting postcards ❤︎ morning glory/flower print/dye ❤︎ #675

For those growing morning glories, I recommend leaf-and-petal rubbing (rubbing dye).

First, prepare morning glory petals and leaves, plus thin paper.

Place a petal between sheets of the thin paper, then rub over it with something that glides easily, like a spoon.

Apply enough pressure to transfer the color evenly without tearing the paper.

You should see the morning glory’s color transferred onto the paper.

Do the same with the leaves.

Then cut out the dyed sections, and you’re done.

It’s great for customizing postcards, too.
