Ingredients & Supplies
🧂 You Will Need:
- Mason Jars – Pint or quart-sized jars work best.
- Filtered Water
- Blue Food Coloring
- Glycerin – Optional, but adds dreamy movement.
- Blue & White Glitter – For sparkle!
- Aquarium Plastic Figurines – Think mini fish, turtles, or sea horses.

Optional Add-ins and Substitutes

Step-by-Step Instructions 🐟
1. Build the Base
Place a layer of aquarium rocks at the bottom of the mason jar. This creates a realistic underwater “floor.”
2. Add Greenery
Nestle in a few plastic plants. Position them upright by tucking them into the rocks.
3. Fill with Water
Slowly pour in filtered water, leaving about 1 inch from the top.
4. Add Figurines
Drop in your toy fish or sea animals and gently use a spoon or skewer to position them if needed.
5. Color Your Ocean
Add 1–2 drops of blue food coloring. Stir gently until evenly mixed.
6. Glitter Time!
Sprinkle in some blue and white glitter for shimmer and ocean “bubbles.”
7. Add Glycerin
Pour in about 1–2 teaspoons of glycerin to slow the movement of glitter.
8. Seal the Magic
Screw the lid on tight. For extra safety, seal with glue or tape.
9. Shake, Watch, Relax
Gently swirl the jar to bring your underwater world to life!
What to Display or Pair It With
- Set beside a storybook about the ocean.
- Use as a centerpiece for a nautical-themed party.
- Display it on a child’s nightstand for a calming bedtime visual.
- Pair with a DIY seashell frame or beachy candle holder for a themed craft day.
Tips for a Perfect Mason Jar Aquarium
- Don’t overfill the jar—leave space for movement.
- Use clear glycerin (found in pharmacies or craft stores).
- Want less mess? Hot glue the lid shut!
- For group projects, prep supplies in advance and label jars.
Storage & Longevity
- Store upright at room temperature.
- Avoid direct sunlight—colors may fade.
- These can last months, even years, if sealed properly!
FAQs
❓ Can I use tap water?
Yes, but filtered water keeps the jar cleaner over time.
❓ Is glycerin necessary?
No, but it slows glitter movement and adds a magical floating effect.
❓ Can I use real plants or fish?
Nope—this is strictly a no-live-creatures project.
❓ Will the food coloring stain?
Not if sealed properly! Just be careful when handling during the process.
