You would be thinking that it is ridiculous to ask something like this. But, solar cooking stoves and nail polish have something in common- a polymer called Mylar.
Mylar is a special type of stretched polyester generally known as BoPET. It is also known as Melinax and Hostaphan. Don’t be confused with too many names. It is made of polyethylene terphtalate (PET) monomers. It is transparent and chemically stable. It also provides good electrical insulation.
Mylar is used for making packaging and lids for food products. It is also used as a covering over paper or clothing. This coating gives a shiny surface and a protective coating. It is used in a range of other products like the diaphragms of headphones.
