Light painting is a creative activity that involves creating striking images and illusions using a camera, a light source, and a little practice.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

This resource contains several mini-explorations using a slide projector as a light source to investigate light and the properties of images.

In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.

In this trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.

Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

This activity provides instructions for building a mirrored tube--a smaller and simpler version of a submarine's periscope--that lets you see around corners and over walls.

In this quick optics activity, learners use a dim point of light (a disassembled Mini MagLite and dowel set-up) to cast a shadow of the blood supply in their retina onto the retina itself.

If you had a long tube with a 5 millimeter wide slit, would you see the entire Golden Gate Bridge?

Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.

An ordinary camera has a lens that makes an image on film. In a pinhole camera, a small hole replaces the lens.

This is an activity to do when there is a solar eclipse!
