"Unbelievable: Magnetized Sand Defies Gravity, Handwritten LEDs Illuminate"
Engineers at Lehigh University have discovered a phenomenon where magnetized sand flows uphill, defying conventional wisdom about granular materials. The research, published in Nature Communications, challenges our understanding of how these materials behave. By using equations that describe the flow of granular materials, the researchers were able to confirm that the particles were indeed moving uphill, contrary to the force of gravity.
