Pillow fight with an octopus—who’s in? ⁠ ⁠ 

These pillows may be a little harder than your average square of fluff! Pillow lavas look like rounded blobs of solidified lava. They are formed as lava pours slowly out of the seafloor, and the outer edge is cooled very quickly by the cold seawater. Think about squeezing toothpaste out of a tube, but instead of it flowing freely, the outer skin of the toothpaste hardens as soon as it touches air. Pillow lavas come in various sizes and shapes, and each of these shapes can tell us a bit about the eruption that formed them.
