(this is probably a bad idea but...) what if the gentleman made a tunnel for the student, were the tunnel is an icosagon (20 sides), and the levels are are like, there are a few strips that all end at the same time, there are an equal number that begin imeadiatlly after, they all look like they line up opposite another, but only one actually does, so the student changes gravity under the one he thinks matches up (and someway to prevent them just shifting)
