Introducing handmade bath bomb ideas! Bath additives that make bath time more fun (1–10)
strawberry
Would you like to try making strawberry bath bombs? The soft pink color is super cute.
Put baking soda, citric acid, and coarse salt in a bowl, then add strawberry powder for coloring and essential oil for fragrance.
It’s best to mix the essential oil into the baking soda first.
After thoroughly combining the powders, add water little by little while mixing and start packing it together.
Once shaped, remove from the mold and let it dry for about half a day.
You can also decorate with dried herbs if you like.
The shelf life is about one month.
Anpanman
Here’s an idea for bath bombs using Anpanman-shaped molds that your child will love.
Mix 100 g of baking soda, 50 g of citric acid, and 50 g of potato starch well.
Then, while spraying anhydrous ethanol, press the mixture together to form it.
It’s ready when it holds its shape without crumbling when squeezed firmly.
After that, just press it into the mold and let it dry.
If you’re making these with your child, be careful to avoid getting anhydrous ethanol on them.
If you’re worried, you can substitute water instead.
Anpanman has many different characters, so try using your favorite molds!
heart
Let’s make super-easy bath bombs by simply mixing 2 parts baking soda with 1 part citric acid and pressing the mixture together while adding a little water! Even kids can make them, so give it a try.
If you want to add color, mix in some food coloring.
You can also swirl in colored powder for a marble effect, add dried flowers for a pretty look, or mix in gold leaf for some sparkle.
There are lots of molds available—balls, hearts, stars, and more—so make your bath bombs in whatever shapes you like.
yuzu
In Japan, there’s a tradition of taking a yuzu bath on the winter solstice.
The refreshing aroma helps you relax, and a yuzu bath warms the body.
It’s also good for dry skin.
Let’s make bath bombs using yuzu.
Mix baking soda, citric acid, coarse salt, and chopped yuzu, then lightly mist with yuzu-infused alcohol made by soaking yuzu seeds, gradually packing the mixture together.
Shape it into balls using plastic wrap, let them dry for about half a day, and they’re done.
It’s a perfect idea for a winter gift.
100-yen shop items
Let’s make bath bombs using items from the 100-yen shop! You’ll need baking soda, citric acid, food coloring, essential oil, and silicone or plastic molds.
Powdered food coloring can sometimes be found in baking supply sections.
To make them, mix the baking soda and citric acid, then add small amounts of water tinted with food coloring while mixing.
Pack the mixture firmly into the molds and let it dry—done! Since you just mix and press it into molds, it’s a fun activity to do with kids.
Using various cute molds or layering different colors also makes them adorable.
Lavender flower
When it comes to relaxing scents, lavender is probably at the top of the list.
Many people name it as a favorite fragrance.
Here’s a handmade bath bomb idea using lavender flowers.
Mix baking soda, citric acid, and sea salt, add fragrance with lavender essential oil, and mist with water as you press the mixture together.
Place lavender flowers in a mold, add the packed mixture on top, and let it dry to finish! You can also add food coloring for a touch of color.
Give it as a gift to someone who’s tired and help them unwind.
LEGO
Would you like to try making bath bombs using LEGO molds? Mix 100 g of baking soda with 50 g each of citric acid and potato starch, and add food coloring.
Then spray in a little water and mix further.
Be careful not to add too much water.
After that, press the mixture into the molds and let it dry to finish.
Use block and minifigure molds to shape them.
It’s fun to stack the blocks and play with them like LEGO, or to spray them with water and let them dissolve little by little.
