The Hourglass (2)

While Conor experiments to try to find the missing part to the Mach 6, he accidentally opens up a time vortex! While the gang tries everything they can, Conor finally figures out a way to close it. Speed must "jump" through the vortex to go into the past. Past Conor doesn't remember a thing, but Speed plays a DVD of "Future" Conor, saying that they must not experiment for the part anymore and that Tuesday is Taco day. Speed and Conor both realize that they must now hunt down the missing part before it gets into the wrong hands.
