@brittany.moonan: Always romanticizing life over here ✨ I love the whimsy but also always need to know the why… Did you know this effect is called caustics. Sunlight passes through moving water and the ripples on the surface act like tiny lenses. They bend and focus the sunlight onto the pool floor, as the water moves, the light shifts, creating those shimmering, dancing patterns…and now you know a fun new fact 💁🏻♀️ #whimsy #thelittlethings #pool #water #oliviadean
