Let’s Make Icicles!

There is scarcely an operation of nature to which we may not find reference in the Word of God. The Word declares that “he maketh his sun to rise,” and the rain to descend (Matt. 5:45). He “maketh grass to grow upon the mountains.” “He giveth snow like wool: he scattereth the hoarfrost like ashes. He casteth forth his ice like morsels. . . . He sendeth out his word, and melteth them: he causeth his wind to blow, and the waters flow” (Ps. 147:8, 16-18). “He maketh lightnings for the rain; he bringeth the wind out of his treasuries” (Ps. 135:7).” Selected Messages, Volume 1, pg. 294.1.

   How do icicles form?

One way icicles form is when the sun begins to melt the snow it drips off of a surface like the roof. But when the melted snow hits the cold air it freezes and begins to form icicles. Now icicles are look like “stakes” and as more melted snow rolls down, it becomes just a little bigger as it freezes back onto the icicle. And up here in New York we have seen icicles taller than people!

Materials

1 dressmaker’s pin
7oz(210ml)paper cup
marking pen
masking tape
tap water
scissors
5-ounce (150ml)paper cup
sharpened pencil
index card
7-ounce (210ml)clear plastic glass
timer
an adult to help you

Procedure
1. As an adult to use the pin to make a pinhole in the corner of the bottom of the 7-ounce (210ml)paper cup. Label Cup “A”.
2. Cover the hole on the bottom of the cup with a piece of tape.
3. Fill the cup three-fourths full with water.
4. Place the cup in the freezer for 30 minutes.
5. Cut a circle from the paper towel the right size to fit in the bottom of the 5-ounce (150ml)paper cup. Insert the paper circle into the bottom of the cup and label this cup “B”.
6. Holding cup B in one hand, push the point of the pencil through the paper towel and out the bottom of the cup three times to create three evenly spaced holes in the bottom of the cup. Some of the paper towel will extend through the holes.
7. Cut a hole in the center of the index card just large enough that cup B can fit into the hold with about 2 inches (5cm) of the bottom of the cup extending below the card.
8. Set cup B in the hole in the center of the card, and place the index card over the mouth of the plastic glass.
9. After 30 minutes remove cup A from the freezer. The water inside cup A should be in liquid form except for a few ice crystals.
10.Remove the tape from the bottom of cup A and place cup A inside B.
11.Place the stack of cups in the freezer for one hour.
12.Remove the stack of cups and observe.
