Jeri Ellsworth made this quick and dirty gas containment chamber for her laser cutter — to be able to test the gases generated from the lasing of various materials — using a silicon wafer (which the beam passes through) and a cookie tin. This rig can also be used to contain materials that might otherwise damage the laser’s optics during the etching/cutting process. Nice job on the video, Jer!
