Draw a picture/figure and press the space key to find out if it can gain lift, and how much. USE TURBO MODE! Here's what lift is: Lift is when air rushes up an object, and makes the air above it faster than the air below. Because their's less air pressure above, the air on the bottom can push the object off the ground.
Remember! This is NOT to measure aerodynamics! It's used to measure lift! My best: 40% lift. Remember that it's basically impossible to get 100% lift.
