Your captors are bubbling air into a water glass from a hose. You are miniaturized and asked if you wish to be placed in a small bubble or a large bubble. All the bubbles appear to be less than 3 millimeters in radius. Your goal is to reach the surface of the water along the straightest possible path. What bubble do you choose?
Answer
Choose a very small bubble. Very small bubbles (with radii less than 0.7 millimeters) are spherical and rise to the surface in a straight line. Bubbles between 0.7 millimeters and 3 millimeters in radius are spherical but either spiral or zigzag upward.Hide Answer Show Answer
