Open the lab door at the end of the hallway by
inputting the code. You'll find it on page 59 of Dr.
Krick's notes.

Dr. Krick's Lab
From the work table to your left, pick up Dr.
Krick's notes, the soldering iron, a small tube near
the back, and a small dark gray wire with silver ends
below the microscope.

Use the crowbar on the silver case twice to open
it, then remove one large tube. Open what looks like
a pot-bellied stove by the control panel, remove the
blown-out tube, replace it with the small one, remove
and replace the burnt wire, then solder both ends.
Click all eight switches plus the left lever on the
control panel.

Go upstairs and open the padlocked door by using
the crowbar on the lock three times. Open the lamp,
remove and replace the large tube, look up and attach
the plug to the lightning rod.

Now leave the lab and the house and go to the shed
and throw that last large circuit breaker. If it
fails to close, you missed something in the lab.

Back in the lab, open the panel in the computer
(it's that red-striped contraption in the corner) and
hit the reset switch. Go to the computer monitor and
click "Retry." If the computer displays an
error message you've missed something along the way.

Now move the right lever on the control panel and
enter the newly generated shimmering portal to the
parallel world.
