Exploration #6

Look through the diffraction grating (clear, but reflections show a bit of color) at a light (not too bright!) What do you see? Try different kinds of bulbs, fluorescents, LEDs, etc. Try a candle flame. If you have a laser pointer, aim it through the diffraction grating to a white wall or piece of paper. What do you see now? Does a red pointer do the same thing as a green one?

Exploration #5

Hold the Magne-View® film to the back of a refrigerator magnet. What do you see? Does the pattern change when you move one or the other? Does it stay when you move the film away from the magnet? What do you see with other magnets? (Note, you can use a flat fridge magnet to “erase” the pattern. Figure out the best way to do it!

Hold the “creation” in front of a computer screen showing a blank white image (an empty word processing window is perfect). Look at it through one of the polarizers. Rotate the polarizer to let as little light through as possible. Rotate the creation. What do you see? If you put the polarizer between the creation and the screen, does it change?

Now make a stack of the two polarizers and look through them. Flip one over. What do you see now? Flip the other. Hold one still and rotate the other like you did in exploration #1. What do you see now?
