+	You have a painting on a string. \par
+	Hang the painting on two nails so that if either is removed, the painting falls. \par
+
+	\vspace{2mm}
+	You may detach the string as you hang the painting, but it must be re-attached once you're done.
+
+	\note{The solution to this problem isn't an out-of-the-box trick, it's a clever wrapping of the string.}

+		Say we have a left nail and a right nail. The path of the string is as follows:
+		\begin{itemize}
+			\item Start on the left

+			\item Wrap left nail ccw
+			\item Wrap right nail ccw
