Sweets Bath Bomb

[DIY] Cute Foamy Treats in the Bath ♡ Sweets Bath Bomb

A bath bomb you drop in the tub to enjoy bubbles and fragrance.

How about making bath bombs that look like fake sweets, with attention to appearance? The ingredients for bath bombs are baking soda, citric acid, cornstarch, aromatic oil, and food coloring.

Mix everything thoroughly, then mist with water to moisten until it holds together.

Next, press the mixture into silicone molds, let it set, and dry.

Then melt glycerin soap in the microwave, tint it with food coloring to mimic chocolate sauce, and drizzle it over the set bath bombs.

Try making a variety of sweet-inspired bath bombs—like donut shapes or chocolate shapes—and have fun!

Let’s make Colorful Joy!

P&G × CAINZ: Let’s Create Colorful JOY!

Here’s a science project idea using dishwashing detergent that both kids and adults can enjoy! Let’s make “Colorful Joy” using the well-known dishwashing detergent Joy from the commercials.

The key to this project is combining the heavier, double-sanitizing Joy with the lighter, regular Joy.

Pour the heavier one into a glass or plastic bottle first, then gently add the lighter one afterward to create beautiful layers! You can try different color combinations, and it’s also lovely to add dried flowers in advance, like a herbarium.

The best part is that after you’re done, you can still use it at home as detergent!

An atmospheric pressure experiment using eggs

Atmospheric pressure experiment (a hard-boiled egg that was sucked into a milk bottle comes back out)

This is an experiment where you can learn how air pressure works using a hard-boiled egg and a bottle! What you need are ice water, a bottle, hot water, and a hard-boiled egg.

Here are the steps: First, place the bottle in hot water to warm it up.

The bottle will become very hot, so when you take it out, be sure to use tongs or something similar so you don’t touch it directly.

Take the bottle out and place the hard-boiled egg over the mouth of the bottle.

While keeping the egg on top, put the bottle into the ice water to cool it down.

As you do this, the air pressure inside the bottle changes, and the egg gets sucked into the bottle.

Watching the egg get pulled in is fascinating and makes for a really fun experiment!

Remaking a 100-yen shop clock

Remake a 100-yen shop clock! Clip clock 👍✨Summer Vacation Craft#Summer Vacation Workshop#100-yen shop DIY#100-yen shop arrangement

Original Song – Nanmo-kun – Broccoli Family

The part you can see from the back of a table clock or wall clock—the section with the battery compartment and the knob for setting the time—is called the movement.

You could say it’s the heart of the clock.

In fact, clock movements are sold on their own at 100-yen shops and home improvement stores, and you can use them to make your own original clock! If you’re good at woodworking, try starting from scratch by buying a wooden board and cutting a groove to fit the movement.

If that’s not your strong suit, there are also assembly kits with pre-cut grooves available, so you can use those instead.

Key rack made from 100-yen shop materials

[100-Yen DIY] Easy Craft: Key Rack and Accessory Holder – Summer Vacation DIY

This is a key rack packed with ideas, made using photo frames.

Prepare three identical photo frames: two will form the body and one will be the lid.

Start by making the body.

First, cut a cork sheet to fit the inside dimensions of a photo frame, apply a decorative remake sheet, and attach it to the first frame.

Next, glue the second frame on top of the first.

That completes the body.

Then, use hinges to connect the third frame to the body as a lid.

Finish by attaching an arch latch.

By inserting aluminum pins into the cork sheet, you can hang your keys on them.

It’s a creative project that turns photo frames into a key rack.

Try painting it or adding your own touches to make it uniquely yours.

How to make strawberry jam

One charm of strawberry jam is its vivid red color and distinctive translucence; it even seems like its appearance enhances its deliciousness.

This project focuses on that colorful aspect of strawberry jam and aims to cutely recreate the look of jam in a small jar.

Use a tiny jar—like the kind that once held craft parts—and pack it with pieces of clear plastic sheet painted red to resemble strawberry jam.

By decorating the inside of the jar, you can convincingly replicate that unique translucence and shine.

It’s also a great idea to plan jar decorations that highlight the contents inside.
