This demonstrates how light is bent as it passes from air (low refractive index) into an acrylic block (higher refractive index). The unbreakable, specially formulated plastic highlights light beams as they bend and pass through. An inexpensive and dramatic way to see refraction and to show critical angle reflection.

Use with any laser, laser ray box or laser pointer.

Size approximately 40mm x 20mm x 70mm.
