鳥兒看起來飛得輕鬆自在，但人類為了讓自己飛起來，可是做了非常多的努力，例如：我們該怎麼對抗讓我們的雙腳「黏」在地表的地心引力？除了往下拉的重力和往上升的升力影響飛行的高度外，向前進的推力和向後推的阻力則影響了飛行的速度。透過親自動手和觀察，我們將一窺自在飛行的秘密，也可以試著想想看，是否還有更多增加升力和突破阻力的可能性？

Flying is easy for birds but requires a lot of effort for humans. For instance, how can we fight against the gravity that pulls us towards the Earth? In addition to the downward pull of gravity and the upward lift that is required to gain height, the forward thrust and the opposing drag affect the speed of flight. Through hands-on experiment and observation, we can take a peek into the secrets of flight. Can you imagine other possibilities to increase lift and decrease drag?
