Snow Globes
Today's
Snack: Let's make edible snowballs! First, wash your hands! Then, with a
large spoon or an ice-cream scoop, pack as much vanilla ice cream as you can
into a one-cup measure. Scoop it out into your clean hands. Form into a perfect
ball. Work quickly so it doesn't melt! Roll in flaked coconut or mini white
chocolate chips. Now place it on waxed paper on a plate or in a dish and freeze
for a few minutes. Don't throw these snowballs - put 'em in a bowl, grab a
spoon, and eat 'em!

Supplies:
Glass jar or bottle with screw-top lid
(The globe-shaped, 13.5-oz., plastic Coca-Cola
bottles available at Christmastime are perfect for this. Or use a clean, empty
baby-food jar or other small, rounded glass jar with tight-fitting lid)
Distilled water or tap water
A few drops of bleach
A few drops of glycerin (available from a pharmacy)
White or silver glitter or foil snowflake cutouts
Waterproof glue (such as Crazy Glue) or silicone
Ribbon or paint to conceal the cap
Whether or not the weather outside is frightful, you
can make a wintry snow scene in a bottle for a mini-blizzard on command.
If you are able to find a plastic or non-rusting
metal figure to glue onto the inside of the lid, so that the "snow" falls down
on it, that makes an even better snow globe. Search at a hobby store for a
plastic mini-evergreen tree, a deer, a penguin, a mountainside cabin or other
wintry objects. You can make them "stand taller" by first gluing a cork to the
inside of the lid, and then gluing the object onto the cork. Remember to use
waterproof glue!
Or just make a plain globe to celebrate the slow
swirling of snow. Fill the globe with distilled or tap water almost, but not
quite, to the top. Measure in a small quantity of glitter or foil cutouts. You
might want to experiment with the quantity first so that it's not too much or
too little. Try a quarter-teaspoon to start.
Then add a few drops of household bleach to keep the
water pure, and a few drops of glycerin to make the "snow" fall more slowly.
Screw the lid on fairly tight. Shake your snow globe once,
to make sure you like the effect. If you do, then screw the lid on as tight as
you can, and go around the outside edge with a sealing "ring" of silicone. Let
dry.
The reason for the silicone "ring" is to keep your
snow globe from leaking. It will also help a lot if you store it with the lid
side up. Be sure to store your snow globe in a place where, if it does leak in
the future, it won't damage any furniture. Putting it inside a Styrofoam bowl
is a good solution.
Also store it out of direct sunlight; it's not
impossible that strong sunlight shining through a window and through the water
in your snow globe could possibly ignite something, the way light shining
through a magnifying glass can start a fire - so never store a snow globe on a
windowsill!
When the silicone is dry, conceal the seam and
beautify the lid with ribbon or acrylic paint, perhaps in black to make it
"disappear" from the snow scene.
A little science note: your snow globe illustrates
something you can observe in real life about falling snow. Snow doesn't fall
straight down, does it? It takes a while to fall, and it swirls around a little
bit, too. Why is that? Because the atmosphere from which snowflakes fall has thickness,
even though it's merely air.
Just as you add a little glycerin to the water to
make your glitter or foil cutouts "fall" more slowly, the atmosphere has volume
to it that makes snow fall slower than it would otherwise. Then the wind can
blow it this way and that, swirling it around and exposing it to different
temperatures at different heights. That's how it can be that each and every
snowflake is a different shape. Each individual snowflake has a different
"journey" to the Earth, and its shape is influenced by wind and temperature as
it falls.
Science and snowflakes: they're both pretty . . .
COOL!!!
