Magnets in mini format

Experience firsthand how tiny iron oxide nanoparticles are created from liquids – using an astonishingly simple method: the tip-and-pour principle. No complicated machines, no white lab coats – just tip and shake!

These mini-particles are true all-rounders: They're magnetic and can therefore be easily "fished out" of a liquid. Sounds like science fiction? But it's real, hands-on science.
