【英语时差8,16】在压力下驾驶（下）

 Surprisingly, if you’ve ever had this experience you might have noticed that the balloons move backwards¹ — just the opposite of your body. Why? It’s because the balloons are floating in the air that fills the car. The air itself is subject to the same acceleration² as your body. When you hit the brakes, the air continues moving forward the same way you do. More air gets pushed to the front than remains³ in the back. So there is momentarily greater air pressure at the front of the car. The floating balloons register this by being pushed backwards. You can try this with a candle inside a glass container. Push the container forward and then stop. The flame will tilt⁴ backward! The air inside has been accelerated so that it briefly⁵ crowds one end of the container, forcing the candle flame back toward the area of lower pressure.
