Magnets

I used to have a set that had magnets inside that would repel each other unless the cubes were in the solved configuration. Anyone know anything about this?

this question from eric osman at rcn dot com 17-feb-2014 : The article says "there is an edge between two vertices if the two colors are on the opposite sides of the cube" . Shouldn't that say "both cubes" or something else ? As written, it is confusing to me, because the two vertices can come from two different cubes, so which of those two cubes are you talking about when you say "the cube"  ?

Thanks. — Preceding unsigned comment added by Ericosman (talk • contribs) 22:48, 17 February 2014 (UTC)[reply]

The text says "The puzzles use a subset of the 30 cubes devised by Percy Alexander MacMahon", but this is incorrect; each of MacMahon's cubes is six-colored. They don't seem to be related at all, except for both puzzles having cubes with the faces colored. I'm removing that line. Joule36e5 (talk) 07:55, 30 June 2015 (UTC)[reply]
