Who doesn't like super strong magnets? No one I know. Some enjoy them because they hold things, others use them for really cool tricks and I just like to try to make them levitate on top of each other. Most of us only use the common refrigerator-style magnet to play with, but have you experienced the power of Neodymium Rare Earth Magnets, better known as Curiously Strong Magnets - The Strongest Permanent Magnets Ever Manufactured ($20)! They're tiny, but they are up to 15x the strength of a common fridge magnet and can lift nearly 400x their own weight in steel. Be careful of pinched fingers and erased hard drives and credit cards with these things.
