I'm rather fond of poetry magnets, and have collected several sets over the years. Here's a grouping from my Jack Prelutsky Awful Ogre's Awful Day set. Somewhere I have a "ransom letter" set from Lemony Snicket's Series of Unfortunate Events, as well.
Several years ago, I had a set of poetry magnets at the library, and the teens loved them. Maybe it's something I should try again. They're not too expensive, either. The original website, Magnetic Poetry, still offers lots of different word collections.
