EXPERIMENT 2
Making a Large Individual Crystal
YOU WILL NEED:
› The remaining crystal solution, a
crystal from Experiment 1, old pot,
trivet, oven mitts, thread
1. Heat the solution in the jar as in
Experiment 1. Stir until all the
crystals have re-dissolved. It will
take a little longer this time because
the crystals are larger. Let the
solution cool for 20 minutes.
2. After the solution has cooled, take
a crystal from your box and tie a
thread around it. Then tie the other
end of the thread to a wooden
skewer or long pencil, and lay the
skewer or pencil across the top of
the jar. The thread should be long

submerged in the solution without
touching the bottom of the jar.
3. Return the jar to its out-of-the-
way spot and wait. The crystal
will continue to grow larger over
the next few days. If a lot of little
Tip!
This is how to label
the mason jars: Write
“crystal salt solution”
with a pencil or
ballpoint pen on a narrow strip of
paper, and tape the paper to the jar. If
you use self-adhesive labels, you
should still cover the label with a strip
of tape.
