Researchers Can Now Create Lenses For Less Than a Penny

It's Easy Bake Oven — science edition.

Researchers at the Australian National University (ANU) have developed a simple, inexpensive method for creating lenses that would open doors for researchers, students and hobbyists.

Lenses are usually made by either grinding and polishing a disk of glass until it is curved or with molds — both costly, complex methods, the former of which has been practiced for hundreds of years. This new process will allow scientists to bake their own lenses by harnessing the power of gravity with only an oven, a glass slide and polydimethylsiloxane (PDMS) — a common, gel-like polymer.
