If you have space fanatics, you have to try this fun craft! You and the kids will have so much fun making this DIY galaxy in a jar project!

Warning, this craft has a generous amount of glitter so if you have sparkalaphobia - or a fear of glitter - this project probably isn't for you. 😃
This DIY Galaxy Jar, or Nebula Jar is a gorgeous craft for kids - and honestly, adults, too!
Having a sensory jar like this is a great way for young children to to relax and have a few minutes of 'calm down' time.
And I find it a great stress relief, too! Taking a few minutes to shake up the jar and watching the glitter swirl around really is therapeutic. The silver glitter makes me think of stars in the night sky, which I love looking at in real life, too.
In this tutorial, we'll show you how to make a galaxy glitter jar. We've used purple paint in three shades to create an Ombre effect.
You can use different colors, but you might want to test them first to see how they look together.
Some galaxy jar DIY instructions do not call for cotton balls, but using them is what will give you the illusion of a nebula cloud.
It doesn't take too much imagination to think of the glitter as baby stars in between clouds of dust and gas in some far off corner of the universe!
Along with this Glitter Slime, these jars would be a fun addition to any rainbow, unicorn, or Mermaid Themed Party

📝Instructions

Step 1: Add water to each glass until it’s about ¾ full. Put 4 or 5 drops of paint in each glass and stir with a popsicle stick. Use a separate popsicle stick for the dark, medium, and light colors. Add 1 or 2 more drops of paint, if needed, to deepen the colors in each glass.

Step 2: Stretch the cotton balls.

Step 3: Put the cotton balls in the jar, filling each one ¼ of the way with cotton balls.

Step 4: Pour just enough of the darkest color of purple paint into each jar to soak the cotton.

Step 5: Add some of the glitter and stars to each jar.

Step 6: Use a popsicle stick to spread the glitter over the cotton balls and around the sides of the jars.

Step 7: Add another layer of cotton to each jar.

Step 8: Grab the glass with the medium shade of purple paint.

Step 9: Pour the medium purple paint over the cotton ball layer in each jar.

Step 10: Add another layer of glitter and stars, using the popsicle stick to spread the glitter around.

Step 11: Add another layer of cotton to each jar.

Step 12: Grab the lightest shade of purple paint.

Step 13: Pour the light purple paint over the cotton layer in each jar.

Step 14: Top with another layer of glitter and stars, using the popsicle stick to spread the glitter around. Finally, top the jars with their lids to seal.

Tips
Be sure to wipe the rim of the mason jar thoroughly before sealing the lid tight. Glitter can sometimes get stuck in the ridges at the top of the jar and prevent a good seal, causing the jars to leak.
How to Make Galaxy Jars
DIY Galaxy in a Jar

Kids will love this out-of-this-world Galaxy in a Jar craft. Sensory jars are as calming as they are beautiful.
Materials
- 3-8-ounce plastic cups
- 3 ombre colors of acrylic paint
- 3 Mason jars
- Large cotton balls
- Regular glitter
- Chunky glitter
- Glitter stars
- Wooden craft sticks
Instructions
- Add water to each glass until it’s about ¾ full. Put 4 or 5 drops of paint in each glass and stir with a popsicle stick. Use a separate popsicle stick for the dark, medium, and light colors. Add 1 or 2 more drops of paint, if needed, to deepen the colors in each glass.
- Stretch the cotton balls.
- Put the cotton balls in the jar, filling each one ¼ of the way with cotton balls.
- Pour just enough of the darkest color of purple paint into each jar to soak the cotton.
- Add some of the glitter and stars to each jar.
- Use a popsicle stick to spread the glitter over the cotton balls and around the sides of the jars.
- Repeat steps 2-6 with the medium purple paint and water mixture.
- Repeat steps 2-6 with the light purple paint and water mixture. After adding the final layer of glitter, put the lids on the jars to seal them.
Notes
- Make sure you add enough cotton to the jars (especially on the sides) to prevent the colors from bleeding into each other. The jars should be almost completely full of cotton.
- When you spread the glitter with the popsicle stick, be careful not to mix up the paint colors, which will muddy the Ombre effect.
