What you'll need
- A magnet
- A mixing bowl (you won't be able to use this for food again, so choose wisely)
- A paintbrush
- A wooden or plastic stir stick
- Iron filings, like from 7th grade science class. You can get them at teacher supply stores, hobby stores, craft stores, online, etc. You can also buy one of those old-fashioned Wooly Willy toys and then crack it open —his "hair" is just iron shavings.
