4" Acrylic Equilateral Prism

My daughter’s third-grade class went wild when we used this prism to scatter rainbows across the whiteboard. The 4-inch acrylic is just the right size for little hands to hold steady. It’s a simple, hands-on way to kick off a science lesson.

We used this prism to show my nephew how white light breaks into color, and it worked perfectly on a sunny afternoon. The 4-inch size is just right for a small hands-on demo without being bulky. Only wish the acrylic felt a bit more durable for repeated use.

Works great for creating rainbows on the wall or ceiling, and the 4-inch size is nice and solid. I just wish the edges were a bit more polished to avoid any sharp feeling spots.
