Space Crafts That Are Out of This World: DIY Galaxy Slime, Nebula Jars, and Star String Art

Crafts That Are Out of This World: DIY Galaxy Slime, Nebula Jars, and Star String Art

Okay, fellow parents, homeschoolers, and tiny human wranglers—brace yourselves. Today we’re going full cosmic chaos, turning your kitchen, living room, and general life space into a glittery, squishy, swirl-filled galaxy. Why? Because crafting is secretly the perfect excuse to explore the universe without leaving your house. And let’s be honest…space is just way cooler than vacuuming.

DIY Galaxy Slime: Squeeze the Universe 

Slime is basically a handheld, squishy, slightly chaotic universe, and it’s perfect for every age. 

You’ll need:

Clear or white glue

Baking soda

Contact lens solution

Food coloring (purple, blue, pink, metallic silver, black for “deep space vibes”)

Glitter, star-shaped confetti, tiny beads, or sequins for meteor vibes

How it works: 

Mix glue and baking soda, swirl in your colors like a mini galaxy, then add contact solution to make the magic happen. The slime should stretch, squish, and bounce back like a cosmic blob from another dimension.

Why it’s awesome:

Toddlers love the sensory experience—squish, stretch, poke, repeat.

Older kids can practice color mixing, layering, and swirling techniques.

Bonus chaos: make multiple slimes and swirl them together—instant cosmic nebula explosion.

Extra tips: Keep an airtight jar handy; this slime can double as a “look but don’t touch” desktop galaxy…until someone inevitably squeezes it.

Nebula Jars: Mini Galaxies in a Bottle.

Nebula jars are like DIY lava lamps met the night sky. 

You’ll need:

A clear jar or bottle

Water

Cotton balls (torn into fluffy cloud bits)

Food coloring in blues, purples, pinks, and a splash of glitter

Optional: glow-in-the-dark paint for a nighttime cosmic effect

How it works: 

Layer the cotton into the jar, then drip in food coloring and glitter between layers. Swirl gently with a stick to create nebula-like clouds. The result? A tiny galaxy in your hands, full of color, shimmer, and chaos.

Why it’s awesome:

It teaches color blending and layering without even saying “science lesson.”

Great for calming sensory play—the swirling effect is mesmerizing.

Bonus: glow-in-the-dark paint makes it perfect for bedtime stargazing indoors.

Pro parenting tip: Let the kids narrate their nebula jars—“This one is Planet Glitterpants!”—because imagination is the best fuel for learning.

Star String Art: Constellations You Can Hang 

String art is the perfect combination of tactile, visual, and slightly OCD-friendly chaos.

 You’ll need:

A wooden board or thick cardboard

Small nails or pushpins

Embroidery floss or colorful string

Hammer (for nails) or patience (for pushpins)

How it works:

Draw star shapes or constellation outlines on your board.

Hammer in nails at each star point.

Wrap string around nails, connecting stars to form constellations.

Why it’s awesome:

Toddlers can choose string colors or wrap string randomly for “chaotic constellations.”

Older kids can recreate actual star patterns—Orion, Big Dipper, maybe even make up their own.

Bonus aesthetic: it looks fancy on the wall even if your life is messy.

Extra chaos factor: Encourage them to make neon or glitter string constellations. Suddenly, your wall is hosting a cosmic rave.

Final Thoughts:

Galaxy slime, nebula jars, and star string art aren’t just crafts—they’re tiny universes of sensory play, color exploration, and chaotic fun. They let kids (and adults, let’s be honest) touch, swirl, and create their own little corners of the cosmos.

The best part? Each craft sneaks in a mini science lesson without anyone realizing: color mixing = chemistry, layering = physics, constellations = astronomy. And you’ll get to say things like “we just made a supernova in a jar!” without needing a PhD.

So grab your glitter, jars, glue, and strings. Embrace the chaos. Celebrate the mess. And remind your little explorers that the universe isn’t neat, and that’s what makes it beautiful.
