After the charge passes through the middle pipe, move Catwoman to the far right panel. After the charge passes through the first movable pipe, move Batman to the far right, but not on the panel just yet. To guide the charge all the way, have Catwoman stand on the middle panel, and Batman on the left, and then start the charge. For reference, Catwoman weighs enough to send a pipe to the bottom line, Batman weighs enough to send the pipe to the middle line, and both standing on the pad wil raise the pipe all the way up. Each of the three pads is pressure sensitive, and will only move the pipe up as far as the weight being applied to the panel. Here you will have to solve the classic 'Guide the electrical charge to it's destination by moving pipes' puzzle, but with a twist. Return once more to the Orphanage and meet up with Catwoman, then enter the new door marked Intro to Physics. This finally ends with a long ramp leading to a platform below, which will require some alternating blocks with the other laps. Following this is several descending platforms you'll need to bring out, followed by a large area that requires a bit of wall driving and block navigating. These paths are followed by a corridor with gaps on the floor, so ride the wall or make paths appear. The race course features a long hallway with multiple doors (more appear in quicker succesion on subsequent laps), followed by a branching path (go left the first lap, right the second, and left the third). To win, you'll need to complete three laps in under the time limit, which means you'll need to be constantly looking out for which panels to open or close.

You'll need to use those same controls to override many of the gates during the race.

As the Riddler drones on about the many rules you'll have to follow, you can either listen to all of them, or just press the prompt to hack the controls opening the gate. Whether or not you decide to follow up on the Riddler sighting early in the game, Mental Blocked is a Riddler-themed race track.
