Your cereal is magnetic 🧲 🥣

3-Second Blueprint (English)

1. Many fortified cereals add metallic elemental iron—around 11 mg per serving—rather than the non-magnetic iron ions found in whole foods.
2. Floating a fortified cereal piece on water minimizes friction, enabling a strong neodymium magnet to pull it visibly across the surface.
3. Blending cereal with water into a thin slurry frees tiny metallic iron flakes that collect directly beneath a strong magnet.
