Kit Contents and Setup
Before beginning your crystal growing adventure, ensure all components are present and prepare your workspace. It is recommended to work in a clean, stable area away from direct sunlight or drafts.
What's Included:
- 3 Crystal Growing Powder packets (one for each color: blue, green, red)
- 3 Seed Crystal Rocks
- 3 Plastic Display Cases
- 3 Beakers (growing chambers)
- 3 Wooden Stir Sticks
- 1 Magnifying Glass
- 1 Learning Guide with instructions and facts

This image displays all the items included in the kit, ensuring users can verify their contents before starting.
Preparation:
- Unpack all items from the box and verify against the "What's Included" list.
- Choose a stable, level surface for your experiment. This location should be cool, dark, and undisturbed for the duration of the crystal growth.
- Ensure you have access to hot water (approximately 140ml per experiment).
Operating Instructions: Growing Your Crystals
Follow these steps carefully to grow beautiful crystals. Each beaker allows for one crystal growth experiment.
- Prepare the Solution: Pour one packet of crystal growing powder into one of the beakers (growing chambers).
- Add Water: Carefully add 140ml of hot water (not boiling) to the beaker with the powder.
- Stir Thoroughly: Use a wooden stir stick to mix the powder and water until the powder is completely dissolved. Ensure no undissolved powder remains at the bottom.
- Introduce Seed Rock: Gently place one seed crystal rock into the center of the solution at the bottom of the beaker.
- Placement for Growth: Move the beaker to your chosen cool, dark, and undisturbed location. It is crucial not to move or disturb the beaker during the crystal growth period.
- Observe Growth: Crystals will begin to form and grow over approximately 5-10 days. Observe the progress daily without disturbing the beaker.
- Harvesting: Once the crystal growth has ceased (typically after 7-10 days), carefully pour out the remaining liquid and gently remove your newly grown crystal.

This visual guide demonstrates the four key steps for successfully growing crystals: adding powder, mixing with water, placing the seed rock, and observing the growth.
Important Note: Each experiment requires precisely 140ml of hot water. The crystal growth environment must be cool and dark, and the beaker should not be moved during the growth period.
Maintenance and Display
Once your crystals have fully grown and been removed from the solution, they require minimal maintenance to preserve their beauty.
Caring for Your Crystals:
- After harvesting, allow the crystals to air dry completely. Do not wipe them, as this may damage their delicate structure.
- Store your crystals in the provided plastic display cases to protect them from dust and physical damage.
- Keep crystals away from direct sunlight or extreme temperature changes, as this can cause them to degrade over time.

Cleaning the Kit Components:
- Rinse the beakers and stir sticks with warm water after use. Ensure all residue is removed.
- The display cases can be wiped clean with a soft, dry cloth.
- All components should be thoroughly dried before storing them.
