These fascinating illusion wires are seemingly never-ending. As they are pulled apart they appear to be untwisting from each other, but they never come apart! Are the wires getting longer? Is it magic? This fun toy can be used to engage students and drive learning about optics, the sense of sight, and the eye-brain connection.

If you’ve ever stood between 2 mirrors facing each other, like in a hair salon, you’re familiar with the seemingly endless line of images seen in the mirrors. The Infinity Mirror recreates this effect. It is just like an ordinary mirror when the built-in mirror lights are off, and the room lights are on. However, with the mirror lights turned on in a darkened room, the effects change dramatically! This is a highly effective way to teach the law of reflection and capture students’ excitement about light and optics.
• Comes with a Teacher’s Guide
• See the product demonstration video on YouTube
• Comes with a fixed power cord with switch, approx. 5 ft in length

This self-contained unit allows students to measure and study light refraction. The angle of incident and refractive rays are readily seen with the help of a built-in laser as its light source. Add water up to the tank’s midline to create a surface that precisely transmits and reflects the laser beam for student observations. The laser revolves around the circular graduated scale and can be set at any point. Students can observe light rays as they travel from air into water, water into air, and water into water. Detach the apparatus from the tank to perform refraction and reflection experiments with the included prisms and mirrors.
Includes:
• 4 prisms
• 2 mirrors
• Laser
• Comes with instructions
• Circular scale is 6.38″ (162 mm) Dia.
