1. How long does it take for the shells to dry?

It usually takes a few hours, but for the best results, allow them to dry overnight.

2. Can I use any type of seashell?

Yes, you can use any type of seashell as long as it’s clean and dry before starting the project.

If the borax doesn't dissolve, the crystals may form unevenly, leading to a less attractive appearance.

With adult supervision, this can be a safe and enjoyable project for older children.

You can experiment with adding glitter or other colorants, but be cautious about using anything that isn’t food-safe.

Prepare the solution: In a container, combine 3 tablespoons of borax powder for every cup of hot water and stir until dissolved.
Add food coloring: Mix in a few drops of food coloring if desired.
Prepare the shells: Tie a string or wire to each seashell if you wish to hang them.
Soak the shells: Leave the shells submerged in the borax solution for about 6 hours or overnight for best results.
Remove and dry: Take the shells out and let them dry to reveal the beautiful crystals formed.

Ensure the borax is completely dissolved for even crystal formation. Experiment with colors and display ideas after drying.
