- Remove Crystals: Carefully take out the crystals and let them dry.
Tips & Variations
- Vary the Borax Amount: Try using different amounts of Borax to get larger or smaller crystals.
- Experiment with Temperature: Conduct experiments with cold water to see if crystals form at different temperatures.
- Add Other Materials: Incorporate different materials like Epsom salt or sugar for unique formations.
Frequently Asked Questions
1. Can I use cold water instead of hot?
While you can use cold water, hot water allows for better saturation, leading to larger crystals.
2. How long does it take for the crystals to grow?
Typically, crystals begin to form within a few hours, but leaving them overnight or up to 24 hours will yield better results.
3. Can I save the crystals I made?
Yes! Just allow them to dry completely and store them in a cool, dry place.
4. What can I do with my crystals?
You can use them for decorative purposes, give them as gifts, or even create unique jewelry.
Suggestions
- Try making crystals in different shapes by using cookie cutters or molds.
- Host a crystal-making party for a fun group activity.
