Tips & Variations:

- Size of Crystals: Adjust the amount of borax for larger or smaller crystals; more borax creates larger formations.
- Add Scents: Incorporate a few drops of essential oil for a scented touch.
- Alternative Containers: Instead of eggshells, try using small containers or jars for a different look.
Frequently Asked Questions:
Q: Can I use something other than borax?
A: While borax is the most effective for crystal formation, you can also experiment with sugar or salt for different crystal types.
Q: How long does it take for the crystals to form?
A: Allow at least 24 hours for optimal crystal growth, but some may take longer.
Q: What if my crystals didn’t form?
A: Ensure that the water was hot enough and the borax was fully dissolved. Try increasing the amount of borax or leaving it for another day.
Q: Can I eat the eggs before using them for this project?
A: Absolutely! Just make sure to clean the shells thoroughly afterward.
