Huygens Optics experiments with etching tiny patterns in glass, covering hydrofluoric acid risks, buffered oxide etch, photoresist and chromium masks, and laser-induced etching. It ends with attempts at microscopic Tesla valves.
Why HN recommends it: HN recommends it as a highly informative look at micro-etching glass and the smallest Tesla valves.
