QUOTE : ARIADNE: Do you use a timer? <br />ARTHUR: No, I have to judge it myself. Once you're all asleep in room 528, I wait 'til Yusuf starts his kick...<br />ARIADNE: How will you know?<br />ARTHUR: His music warns me it's coming, then the van hitting the barrier of the bridge should be unmistakable-that's when I blow the floor out from underneath us and we get a nice synchronized kick. Too soon, and we won't get pulled out; too late and I won't be able to drop us.<br />ARIADNE: Why not?<br />ARTHUR: The van will be in free fall. I can't drop us without gravity.
