A New Way to Explore Properties of Light!
Grow Lenses begin as small pebbles - just 3mm across. Soak them in water overnight, and you'll have 3cm transparent gel-like marbles and blocks that are perfect for individual desktop explorations of light and refraction! Use any laser pointer, and students will begin the inquiry process themselves. In their grown state, Grow Lenses can be cut into different shapes, hemispheres, rectangular prisms, triangular prisms, and more. You can even soak them in colored water to produce colored lenses!
