There's really no arranging necessary; the researchers are camped out in the Discovery Center waiting for test subjects voluntary participants to wander through.

The weekend after Thanksgiving may not work, though; it's reasonably likely that the undergrad doobies are on vacation, so there may not be any researchers there that Saturday.

The Discovery Center is part of the museum, so you'd need general admission tickets, but I have some free passes, and with a little planning I could get them to you.
