Magnetic Putty

Here at Just What I Wanted, we can never get enough magnetic stuff. Eventually, the magnetic force exerted by the various items spread throughout our apartment will cause the entire building to implode, reducing yours truly to a tiny yet incredibly massive black hole. Anyway, this Magnetic Putty is full of ultrafine iron powder, which means you can do cool things like make it deform by placing magnets near it. Combine this with some Rare Earth Magnets and you'll have a gooey magnetic mess in no time! $8.95 USD.
