How to Make a Universe Glow Jar

Clean the jar thoroughly and let dry. If you try to make your DIY galaxy glow jar with a wet jar, the paint won’t stick.

Choose a couple of colors you want for your glowing galaxy glow jar and squeeze a bit of each color onto a piece of scrap paper.

The best way to get an even coverage is to dot the paint on with a paintbrush starting at the bottom and working your way up.

A faster way is to shake the paintbrush in the jar to create a splatter paint effect.

Add larger dots for “planets” in your universe. If you want to get creative, make a constellation or a comet!

Let your jar dry in the sun or under a bright light for at least 2 hours to charge the paint.

Turn off the lights and enjoy your beautiful Universe in a Jar – it can be used again and again!

FAQs About Universe Jars

Q: Can I use acrylic paint for a universe jar?

A: Yes, you can use any type of glow-in-the-dark paint. 

Q: Does my jar need to have a lid?

A: No, your jar doesn’t need to have a lid. We hang ours outside in the sunshine to charge, so we make sure they have lids to keep bugs out, but it doesn’t affect how well they work.

Q: What size of glass jar do I need to make a universe jar?

A: Any size of clear glass jar will work. This is a perfect project to recycle glass jars! If the jar is too small to reach the brush inside to paint dots, then it’s too small. Otherwise, you can use whatever glass jars you have around.
