Full Step-by-Step
Prepare the Planets
- Choose your colors: Decide on the colors for each planet. The classic blue, red, and green shades work beautifully for Earth, Mars, and Venus.
- Create your planets: Use foam balls or mold clay into different sizes for varying planet representations. Feel the texture of the materials as you shape them.
- Attach wire: If using wire, cut pieces long enough to suspend your planets inside the jar.
Assemble the Jar
- Paint the base: Use blue and black paint on the inside of your jar to create a night sky effect. Feel the smooth paintbrush glide across the glass.
- Add glitter: Sprinkle glitter on the wet paint to mimic stars sparkling in space.
- Let dry: Give your painted jar time to dry completely.
Insert the Planets
- Arrange the planets: Once dry, carefully place your planets inside, hanging them from the lid if desired. Adjust their heights for an appealing arrangement.
- Secure everything: Use hot glue to ensure the planets stay in place if needed.
Light It Up (Optional)
- Add LED: If you want your jar to glow, place a small LED light at the bottom and cover it with some decorative material.
Tips & Variations
- Custom Colors: Swap out the paint for other colors to represent different seasons or planetary themes.

Frequently Asked Questions
1. Can I use plastic bottles instead of glass jars?
- Yes, clear plastic bottles work just as well and are safer for children.
2. What if I don’t have foam balls?
- You can create planets from paper mache or even ping pong balls for a fun alternative!
3. How do I store my floating planet jar?
- Store it in a cool, dark place to protect it from dust and sunlight, which might fade the colors.
4. Can I use regular glue instead of hot glue?
- While hot glue is recommended for quick-drying, you can use regular craft glue but allow for extra drying time.
