🧲 There’s Magnetic Sand at the Beach?!

Ever noticed the black streaks in the sand at the beach? That’s often magnetite — a naturally magnetic mineral hiding right beneath your feet! In this video, we take you Beachcombing with Jace Tunnell and Dr. Mark Besonen to explore what magnetite is, where it comes from, and why it shows up along the shoreline. We’ll talk about how waves and currents naturally sort heavier minerals like magnetite into those dark sand deposits you sometimes see after a storm. I also demonstrate one of magnetite’s coolest properties — it sticks to a magnet! Watch as I collect it straight from the sand and show how strongly it responds. Plus, I share incredible close-up microscope footage so you can see what magnetite grains actually look like up close. The tiny details might surprise you! If you love beachcombing, geology, coastal science, or just discovering hidden treasures in the sand, this one’s for you!
