Can you please explain what it actually is? I am so confused.

Shuva, it's a cylinder with lots of mirors inside, at the end of the cylinders there is a lots of spangles and yellow powder. You look throught the cylinder and the mirror give a strange result because one spangle is duplicate lot's of time. I will take a photo of out side the kaleidoscope, and send it in a few days, perhaps it will help you to understand, I'm not sure of the quality of my explanation.

More explanations : A tube-shaped optical instrument that is rotated to produce a succession of symmetrical designs by means of mirrors reflecting the constantly changing patterns made by bits of colored glass at one end of the tube. kaleidoscope (kəlī'dəskōp) , optical instrument that uses mirrors to produce changing symmetrical patterns. Invented by the Scottish physicist Sir David Brewster in 1816, the device is usually a hand-held tube, a few inches to as much as twelve feet in length, and looks like a small telescope. At one end of the tube is an eyepiece; at the other end colored chips of glass are loosely sandwiched between two glass disks. Between the ends of the tube are two rectangular plane mirrors. The long edge of one of the two mirrors lies against the long edge of the other at an angle, their intersection lying close to the axis of the tube. The glass chips form patterns where they lie, and these patterns change as the chips fall into new positions when the tube rotates. Each pattern undergoes multiple reflections in the mirrors in such a way as to produce a resulting symmetrical pattern as seen through the eyepiece. The world's largest kaleidoscope, located in Shandaken, N.Y., is 37 feet tall. There is no eyepiece, but as many as 20 people inside the base can view the image, which is projected downward onto three mirrored panels to produce a spherical cluster of 254 hexagonal facets that appears to be 50 feet across.
