Bottles, bubbles and breakages
Party tricks in the science classroom? This video shows how a rubber hammer striking the mouth of a glass bottle filled with water can cause the bottom of the bottle to shatter or fail. Researchers explain how it was previously thought that the bottom of the glass was shattered by a pressure wave. Jesse Daily and Tadd Truscott of Bringham Young University use high-speed video photography and an accelerometer to determine what causes the failure of the bottom portion of water-filled glass bottles. Teachers can find a lesson plan relating to this video here.
