Duck Into Kaleidoscope

With this mirrored kaleidoscope, you can create hundreds of images of whatever you place inside. The basic structure is a triangle, but mirrors can be formed into other shapes and angles as well.

Note: While Snacks were originally conceived to require only low-cost materials, a few Snacks—such as this one—use materials that are notably costly (although there is a reasonable chance these materials might be found in a middle- or high-school classroom). If your school has such items, then this Snack may be appropriate. If not, its usefulness may depend on your ability to obtain or improvise suitable substitutes.
