A chromatrope is a colour changing mechanical slide introduced for the first time by Sir David Brewster in 1846. The moving parts inside the chromatrope are responsible for the changing patterns. It is made up of several disks of glass that rotate by the help of an exterior handle. The handle is not directly fixed to the disks of the glass but to a series of gears that turn the glass disks.
The glass disks are painted in different colours and designs. When the designs are lit behind by a magic lantern, the changing patterns can even be viewed on a wall. Though chromatrope is no longer being made in today's times, the kaleidoscope with its enchanting display of designs in glass continues to delight adult and children alike.
