Hooked on Science: Expanding water

Thursday, December 16, 2010

It's that time of the year when the cold weather can freeze your pipes. Using a few materials from around the house, you can learn the science behind how freezing water can burst your pipes.

Materials

* Water

* Plastic bottle with lid

* Freezer

Instructions

STEP 1: Fill the plastic bottle to the top with water and tightly twist the lid on the bottle.

STEP 2: Place the water-filled bottle into the freezer overnight.

Explanation

As the water freezes it expands and requires more room. Therefore, as the frozen water expands it eventually breaks the plastic bottle.
