KENTUCKY (12/18/12) – Do you have any Christmas tree icicles left over after decorating the tree? If so, using a balloon and a few other ingredients from around the house, you can make them float in the air.
• Christmas Tree Icicles
• Wool Cloth
STEP 1: Cut three pieces of Christmas tree icicles about 6 inches in length.
STEP 2: Tie a knot at each end of the Christmas tree icicles. Use scissors to remove any excess icicles beyond the knots.
STEP 3: Blow up the balloon. Charge the balloon by rubbing it vigorously with the wool cloth.
STEP 4: Hold the Christmas tree icicles near the charged balloon. Once the icicles are attracted to the balloon let go. Quickly pull the balloon away so the icicles do not attach to the balloon. With a lot of practice you can get the icicles to hover in the air above the balloon.
You gave the balloon a negative charge by rubbing the wool cloth on the balloon. The faster you rub the balloon with the wool cloth the more the balloon is negatively charged. The Christmas tree icicles have a positive charge until they touch the balloon. Like charges repeal while unlike charges attract. Now that the Christmas tree icicles have a negative charge and the balloon has a negative charge they should repeal causing the icicles to hover in the air above the balloon.
