What is a prism for kids?

A prism is a solid shape that has two identical ends, called bases, and flat sides. It can be made from materials like glass or plastic, and when light passes through it, a prism can split the light into a rainbow of colors. You can think of it like a special type of box that helps us see all the colors hidden in white light. Prisms come in different shapes, like triangular and rectangular, depending on the shape of their bases.
