And does it matter? Well if a puppy is a candidate to be a guide dog, it may affect its chance of passing or failing school. Jonica Newby reports.BUBBLE BEHAVIOUR (Physics, fluid dynamics)When ships are moving through water at high speeds, the physics creates some surprising effects. Metal can be eaten away by violent explosions - of tiny bubbles. It's known as cavitation and its destructive power can cause equipment failure in not only marine craft, but dams and generators that come into contact with powerful flows of water.
