What You’ll Need:
Note: Making your Crystal solution is a time-sensitive experiment. To increase your
chances of success, before you begin, gather and prep all of your ingredients, set up your
workspace, and thoroughly read all of the safety warnings, directions, and tips.
WARNING: Adult supervision required.
A stainless steel pot or an electric tea
kettle to boil some water. (Filtered
or distilled water is recommended.)
Note: Do not use an aluminum pot.
A glass measuring cup.
A medium-sized mixing bowl (1 to 1.5
quarts). Note: You can mix the Crystal-
growing powder directly in the pot, just
make sure after evaporation you are left
with 1 cup of hot water.
A Crystal-growing chamber, such as
a pint glass or a jar. It should be clear
and heat proof.
Newspapers or cardboard to place
below your experiment to help
prevent the solution from spilling
onto any surfaces.
A Crystal-growing area: Find a
location where your experiment
can remain undisturbed for 7-10
days. There are three things your
area should have: stability, light,
and warmth. Vibration will impede
the Crystal growth, so place your
Crystal-growing chamber in a
spot where it won’t be affected
by surrounding movement. Light
and warmth will make the water
evaporate faster. We recommend 68°F
(20°c). (Your Crystal will still grow in a
cooler, darker spot—just not as fast or
as large.)
