Preparing the plastic
cone
You will need:
Transparent plastic cone, dry crystals
from Experiment 1, sturdy string,
scissors, ruler, all-purpose glue,
tweezers
Here’s how:
1
Cut two pieces of string, each
about 20 cm in length. Tie each
one tightly to one of the little
“feet” of the plastic cone. Trim a
little of the extra string from the
short end where you tied it.
2
Now glue the little crystals all
around the outside of the plastic
cone. Do not fill the flat end
where the opening is! The best
way is to cover one half and let
the glue dry before continuing
with the other half. You can use
a pair of tweezers if you like. Let
the cone dry overnight.
You can put any extra crystals
in the closed jar with the alum
solution. Be sure to wash your
hands very thoroughly after this
experiment!
GEEK
OUT!
WHAT’S
HAPPENING?
Your big crystal is going to grow
on the plastic cone. For that to
happen, the crystal salt particles
in the alum solution will have
to accumulate on the cone. Since
the particles prefer to attach
to already-present crystals, the
first step was to glue on the little
starter crystals.
TIP!
Have a friend hold the plastic cone
while you tie the knot.
