An easier way to rob the Louvre

In a recent video, I said that knots can only be tied in three-dimensional space. Piggly wiggly commented, saying, "In other words, if we have a knot we can't untie, we just have to raise it into a higher dimension where it will fall out." That's a great tip for anyone who has to untangle a box of jewelry. And indeed, it is a good way to untangle headphones, necklaces, or even to unlink rings, allowing them to separate in an extra dimension of space. But you could also use a trip to the fourth dimension to steal jewelry from, say, a fancy museum, and you wouldn't even need to cut through the walls to do it. Instead, from your four-dimensional vantage point, you could look down upon the jewels and pluck them right out, as if you were looking down on a 2D blueprint of the building.
