Magnetic Acrylic Rubik's Cube

Step 5 Get your polarities straight

It's crucial that all these axially-polarized disc magnets are put in the right way, and I'm glad to say I didn't mess this up once in all 108 magnets. To keep me straight as to which side of each magnet was which, I stuck them all together in one long rod, then drew a Sharpie dot on one end, and peeled that magnet off, and repeated, all the way down. Now they all had a visible polarity, though I don't know still which was N or S.
