4" Acrylic Equilateral Prism

My kids have been fighting over whose turn it is to hold it during our kitchen-table science time. The acrylic is crystal clear and the way it splits sunlight into full rainbows across the wall never gets old. Perfect for a quick afternoon demo that actually sparks questions.

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.
