KENTUCKY (12/11/12) – It may not be cold enough outside for snow, but you can still build a snowman and it will even "melt." Jason Lindsey aka "Mr. Science" with Hooked on Science shows us how to create a "melting snowman" by using a few ingredients from around the house.
• Elmer’s Glue
• Large Ziploc Bag
• Snowman Eyes, Scarf, Hat, and Arms
STEP 1: Pour 8 ounces of Elmer’s glue into the large Ziploc bag.
STEP 2: Mix 2 teaspoon of Borax into 1 cup of warm water.
STEP 3: Mix the Elmer’s glue with the water and Borax inside the large Ziploc bag.
STEP 4: Remove the contents from the Ziploc bag. Separate the contents into three pieces. Create a large piece, a medium piece, and a small piece. Form each piece into a sphere. Create a snowman. Allow your snowman to set on a flat surface for a few hours.
After a few hours your snowman will “melt.” Scientifically speaking, the snowman is not actually “melting.” Water freezes at 32 degrees Fahrenheit and 0 degrees Celsius. This experiment has a lot to do with the long chains of molecules in the Elmer’s glue, not freezing and thawing. The Elmer’s glue has a lot of long chains of molecules that freely move past each other. When the Borax solution is added to the Elmer’s glue, the long chains of molecules are linked together. This causes the long chains of molecules in the Elmer’s glue to not move so freely past each other. Therefore, it takes longer for the chains to move past each other and after a few hours your snowman “melts.” Go to www.hookedonscience.org for more experiments that might get you and your family “Hooked on Science.”
