Making a Universe in a Jar is a simple, beautiful DIY craft that brings the wonder of the cosmos into your home. Using just a few household items, this craft offers a hands-on way to express creativity and create a stunning decorative piece.

In this guide, you’ll learn how to make a Universe in a Jar step by step, plus we’ll explore the benefits, expert tips, and FAQs to help you customize it your way.

Instructions (Step-by-Step)

Start with the blue layer:
Fill one-third of your jar with water. Add a few drops of blue food coloring and stir until fully blended.
Add cotton and glitter:
Gently push in cotton balls until they reach the surface of the water. Sprinkle in some glitter and stir gently with your stick to disperse it.
Create the middle cotton layer:
Add more cotton balls to fill the next third of the jar. These should remain mostly dry to create a soft, fluffy layer.
Mix the red color:
In a separate bowl, mix water with a few drops of red food coloring. Stir well to create a vibrant mixture.
Pour in the red water:
Carefully pour the red water into the jar over the cotton, allowing it to seep down gently. Add another sprinkle of glitter for extra sparkle.
Top with final cotton layer:
Add a final layer of cotton balls to fill the jar. This layer will absorb some of the red, creating a colorful swirling effect.
Seal and display:
Place the lid on tightly. You’ve now created your own mini universe! Set it somewhere it can shine with the light, like a windowsill or shelf.

FAQ – Universe in a Jar

Q: Can I use paint instead of food coloring?
Yes, you can dilute acrylic paint in water as a substitute. It gives a rich color effect and works just as well.

Q: Is this safe for children?
Absolutely. With adult supervision—especially with small items like glitter—it’s a kid-friendly craft.

Q: How long will it last?
As long as the lid is tightly sealed, your Universe in a Jar can last for years without fading or leaking.

Q: Can I make different themes?
Of course! Try an “Ocean in a Jar” using greens and blues, or a “Sunset Jar” using orange and yellow.

Q: What kind of jar works best?
Transparent glass or plastic jars with wide openings work best. Mason jars, baby food jars, or even recycled bottles are great choices.
