When these vibrations pass through a surface or a medium, they transfer energy and make the particles move. At certain sound frequencies, the vibrations create areas that move and areas that stay still. The particles gather in the still areas, called nodes, forming clear geometric patterns that we can see. This effect is known as cymatics. Different sound frequencies create di

When one gecko is in danger, another may linger nearby, make abrupt movements, or deliberately expose itself to pull the predator’s focus away.
