1. Introduction
The NATIONAL GEOGRAPHIC Mega Crystal Growing Kit allows children to explore the fascinating world of crystallography by growing their own vibrant crystals. This kit provides all necessary components for a hands-on STEM learning experience, culminating in a beautiful display of self-grown crystals.
2. Safety Warnings
Adult supervision is required for all experiments.
- Read these instructions thoroughly before use. Keep them and the box for future reference.
- Keep the crystal growing solution and finished crystals away from the mouth and eyes.
- Store all experiment components and the final product out of reach of children under 8 years of age.
- Ensure that empty containers and/or solutions are properly disposed of according to local regulations.
- Clean all equipment thoroughly after use.
- Do not eat or drink in the experiment area.
- Do not allow chemicals to come into direct contact with skin or eyes. In case of contact, rinse immediately with plenty of water and seek medical advice if irritation persists.
- Do not apply any substances to the solutions or your body.
- Only use equipment specifically recommended in these instructions for use.
- Do not grow crystals in areas where there is a risk of inhaling the solution. Ensure good ventilation.
- The crystal growing solution is corrosive. Handle with care.
- Always wear protective eyewear during the crystal growing process.

3. What's Included
Your NATIONAL GEOGRAPHIC Mega Crystal Growing Kit contains everything required to grow six vibrant crystals and display them:
- 6 packets of crystal growing powder (various colors)
- 6 clear crystal seed rocks
- 4 real gemstone specimens (Rose Quartz, Fluorite, Blue Calcite, Quartz Geode)
- 2 flexible silicone growing chambers
- 1 light-up crystal display stand (USB powered)
- 1 wooden stirring spoon
- 1 magnifying glass
- 1 full-color STEM learning guide with detailed instructions
- 1 USB power cable for the display stand


4. Setup
Before beginning the crystal growing process, ensure you have a clean, flat, and stable surface. Gather all kit components and ensure you have access to hot water (adult assistance required for handling hot water).
- Prepare Your Workspace: Lay down newspaper or a protective covering to prevent spills.
- Read the Learning Guide: Familiarize yourself with the entire process by reading the included full-color STEM learning guide. Pay close attention to the safety rules.
- Assemble Display Stand: If not already assembled, connect the USB cable to the light-up display stand. The stand is powered via USB and does not require batteries.
5. Operating Instructions: Crystal Growing Process
Follow these steps carefully to grow your crystals. Each crystal growing powder packet is for one crystal.
- Mix with Water: Carefully pour one packet of crystal growing powder into one of the silicone growing chambers. Ask an adult to slowly add hot water (not boiling) to the chamber, stirring gently with the wooden spoon until the powder is completely dissolved. Do not fill past the indicated fill line.
- Pour Solution: Once the powder is dissolved, let the solution cool for a few minutes.
- Add Seed Rock: Carefully place one clear crystal seed rock into the center of the solution in the growing chamber. Ensure it is fully submerged.
- Observe Growth: Place the growing chamber in a safe, undisturbed location at room temperature, away from direct sunlight or drafts. Over the next 3-4 days, observe as the crystals begin to form and grow on the seed rock. Avoid moving or disturbing the chamber during this period.
- Harvest Crystals: Once the crystals have reached their desired size (typically 3-4 days), carefully remove them from the solution. Rinse them gently under cool water to remove any excess solution, then pat dry with a paper towel.
- Display: Place your newly grown crystals onto the light-up display stand to showcase their vibrant colors. The stand can hold up to 5 crystals.


6. Maintenance
Proper care ensures the longevity of your crystals and kit components:
- Crystal Care: Grown crystals are delicate. Handle them gently to avoid breakage. Keep them away from water and high humidity, as this can cause them to dissolve over time.
- Cleaning Components: After each use, thoroughly rinse the silicone growing chambers, wooden spoon, and magnifying glass with cool water. Allow them to air dry completely before storing.
- Display Stand: Keep the light-up display stand clean and dry. Wipe it with a soft, dry cloth if needed. Do not immerse it in water.
- Storage: Store all kit components and finished crystals in a cool, dry place, away from direct sunlight and extreme temperatures.
7. Troubleshooting
If you encounter issues during the crystal growing process, consider the following:
- No Crystal Growth:
- Ensure the water used was hot enough to fully dissolve the powder.
- Verify the seed rock was fully submerged in the solution.
- Check that the growing chamber was placed in an undisturbed location at a consistent room temperature (around 20-25°C or 68-77°F). Drafts or temperature fluctuations can hinder growth.
- Allow sufficient time (up to 4 days) for initial growth to become visible.
- Small or Irregular Crystals:
- This can be caused by too rapid cooling or disturbance during growth. Try to maintain a stable environment.
- Ensure the solution was not over-diluted with too much water.
- Light-Up Stand Not Working:
- Check the USB cable connection to both the stand and the power source (e.g., USB wall adapter, computer USB port).
- Try a different USB power source or cable to rule out a faulty component.
