- Container to hold water centered at the focus
This simple device gives a graphic demonstration of the sun’s radiative energy. A large convex mirror concentrates solar radiation onto a small container of water suspended at the mirror’s focal point. In a few minutes, the water boils.
The mirror’s angle is adjustable though 180° to allow it to be aimed at the sun at any time of day.

Aperture area: 700 cm2
Mirror focal length: 16 cm
Furnace capacity: 20 ml
Base diameter: 22 cm
Height: 33 - 45 cm
