How to Make Salt Crystals

from wikiHow – The How to Manual That You Can Edit

Boredom blues? Science crave? This fun and interesting project will cure both!

Steps

  1. Fill a glass jar about halfway with tap water.
  2. Add some food coloring for a pretty color. Add as much as necessary to the water to get the desired color(optional).
  3. Add about 2-3 tablespoons of salt to the mixture and stir with a spoon until you can’t see the salt grains, then put more salt in it and shake it!
  4. Tie a string around a pencil or small stick.
  5. Cut the string so that it hangs just above the water.
  6. Balance the pencil on top of the glass jar with the string hanging inside the jar just above the water.
  7. Leave it on a table for 1-3 weeks and check back every day to see if there are salt crystals on the string.

Tips

  • Use a thin, but sturdy, string.
  • Use bold shades of food coloring, like bright ruby red or sapphire blue, for an interesting effect.
  • Heating the water up before adding the salt will help the salt dissolve faster (ask an adult to help for this part).
  • Alternatively, you could put the string in the water and see what happens.

Warnings

  • Don’t eat the salt crystals
  • Ask an adult before doing this experiment.

Things You’ll Need

  • 1 glass or cup
  • Tap water
  • 2-3 tablespoons of salt
  • 1 string and 1 pencil, stick, or blunt butter knife
  • Food coloring (optional)
