To have lots of Fun with the Sun, a strip of flexible mirror about 4" wide by 2' long can be key. You put a straight handle on each end, to make it easy to bend and twist the mirror. Then, you go into a blacked-out room whose only source of light is a few prisms in full sunlight. Picking a handy beam of colours, you reflect it from your mirror either directly onto a wall or ceiling, where you can readily make it assume fantastic, dancing shapes, or onto a pile of wrinkled aluminum foil and other reflective trash, which will fill the room with fainter patterns. It goes well with music.
Getting sunlight onto the prisms, such as a very good octagonal chandelier jewel, is best arranged with a Spectral Bazooka. A cardboard tube pokes through a blacked-out window, with the prisms at the inside end. Outside is a mirror hinged to one side of the tube. It can be adjusted for angle by pulling its support string from inside, and by rotating the tube.
