    The crystal will grow based on the shape you submerge in the jar. If you want a crystal with pronounced spikes, you could take a single pipe cleaner and twist smaller lengths of pipe cleaner onto so that they're sticking straight out, perpendicular to the longer piece.

    Expert Answer
    Yes. You want there to be more solid particles than the water can dissolve, so that the crystals can form.
  • Question

    Community Answer
    Wurtzite boron nitride and lonsdaleite (hexagonal diamond) are the two strongest.
  • Question
    Do I need to use food coloring?

    No, because food coloring is just for looks.
  • Question
    Can I grow crystals in a cold environment?
    Community Answer
    Yes, you can.
  • Question
    Can I grow crystals using other crystals?
    Community Answer
    Yes. Put a crystal in a solution, allowing other crystals to grow on the original one.
  • Question
    How do I grow salt rock crystals?
    Community Answer
    You mix salt into a container of water, bit by bit, until the salt stops being able to dissolve. Then you usually pour it onto a flatter surface (like a plate) to dry faster. Let it sit for a while and crystals will form.
  • Question
    How do the crystals grow?
    Community Answer
    The molecules of the chemical (salt, sugar, calcium carbonate) fit together as they leave the solution and join earlier molecules. The solvent (water, oil, alcohol, etc.) can dissolve only a certain amount. If you add more, it becomes supersaturated and the excess starts piling up on the substrate (the string, rock, or small crystal of the same chemical).

    Alum is a kind of spice. Get it in the spice section in your grocery store.
  • Question
    How are salt crystals formed?
    Conner Potts
    Community Answer
    Certain molecules in the liquid gather together as they attempt to become stable. They do this in a uniform and repeating pattern that forms the crystal. In nature, crystals can form when liquid rock, called magma, cools. If it cools slowly, then the crystals may form.
  • Question
    Do I need to use aluminum?
    Community Answer
    No, you can use salt or sugar as well.
  • Question
    Can you grow crystals inside crystals?
    Community Answer
    No, crystals aren't hollow.
  • Question
    What happens if two different salts are used together?
    Community Answer
    The crystals will be the same. It's just salt, so it will not make a difference.
  • Question
    How much sugar is needed for a pint jar to make rock crystal?
    Community Answer

  • Question
    Can I grow crystals onto a smooth surface such as glass?
    WildAnimalGirl
    Community Answer
    Surface crystals rise substantially above the glass surface as they grow laterally without penetrating deep into the bulk.
  • Question
    I made the Borax crystals, but the bottom of the jar crystallized, and I haven't been able to get them off. How could I get them off?

    Community Answer
    Remove Borax crystals by using hot water (as hot as you can stand it) and liquid dish soap.
