Where: In the scene where Bond and Wai Lin are on a Motor Bike being chased by a helicopter, go to the part where they ride out of a apartment down some big crates.
What: Wai Lin is on the back of the bike holding onto the handle bars (they are hand cuffed to each other), and as they go down you can see her arms stretch almost double the normal length!
Why: I did some research and found out that there were springs in her sleeves. The crates are stacked up like stairs, but the shaking of the bike would have broke her arms. The springs acted
as "shock absorbers".
