Sparkleballs Using the "Wrong" Cups
|
The
formula for making a sparkleball
will work with any size or shape of plastic cup.But you have to modify
the basic design. How? |

The
rogue sparkleballer's secret weapon.
|
Form
a circle with the cups you want to use. (these are 5
1/2 oz) Measure the diameter across
the circle with a ruler or measuring tape in several
directions to make sure you've got a perfect circle.
Try removing or adding a cup to see if the circle improves.
Once it's perfect, make a note of how many cups are
in this first layer. (18 5 1/2
oz cups in first layer)
|
Add
a ring of cups on top of the first layer to make the
second layer of cups. Then make the third, fourth, or
even fifth layer to finish the half. (on this one, the
last layer had 1 cup.) Make notes as you complete a
layer so you'll remember how many cups in each one.
I
often clip both halves together to make sure they'll
make a round ball before I attach the cups.
Now
make your unique sparkleball using your new modified
formula.
|
The
5 1/2 oz cup (right) has straighter
sides than the Solo-style 9 oz cup (left). So even though
it's smaller, it takes twice as many to make a sparkleball.
(116 vs 50) Straighter sides mean that it will take more
cups to make your sparkleball turn out nice and round.

It takes
23 16 oz cups (Chinet Casuals) for the first layer of a giant sparkleball
(27" diameter).
|
These
are small 3 oz bathroom cups from CVS pharmacy. It takes
21 cups for the first layer! (oooops. not quite a circle.
this one needs work.)
|
I
can't wait to make this one. These are 5 oz tumblers I
found at Party City. It takes only 10 of these for the
first layer. Precious!
|
All
of these sparkleballs - giant to tiny - were made by modifying
the basic sparkleball
formula.
