The image shows a tall glass cylinder with a transparent base. Inside the cylinder, there are three small glass spheres of different colors - red, blue, green, and purple. The red sphere is on top of the blue sphere, the green sphere is in the middle, and the purple sphere is at the bottom. The glass sphere has a small metal ring around it, which is likely used to hold the spheres in place. The cylinder is sitting on a reflective surface, and there is a blurred background behind it.
