First you need to scrape off the the CD with a knife or a sharp
utensil. you then hold the flame under the Clear CD for about 15sec
untill you see it about to drop down. the Plastic will melt and create
a small bubble right before its about to drop blow into it. not to hard
or the bubble will collapse and cave in on itself. blow at a normal
speed to get a nice long Bubble that wont collapse.

A CD is made from 1.2 mm thick, almost-pure polycarbonate plastic and weighs 15–20 grams. From the center outward, components are: the center (spindle) hole, the first-transition area (clamping ring), the clamping area (stacking ring), the second-transition area (mirror band), the information (data) area, and the rim.

A thin layer of aluminium or, more rarely, gold is applied to the surface making it reflective. The metal is protected by a film of lacquer normally spin coated directly on the reflective layer. The label is printed on the lacquer layer. Common printing methods for CDs are screen-printing and offset printing.

CD data are stored as a series of tiny indentations known as “pits“, encoded in a spiral track molded into the top of the polycarbonate layer. The areas between pits are known as “lands”. Each pit is approximately 100 nm deep by 500 nm wide, and varies from 850 nm to 3.5 µm in length.
