Cloud Room Video Clips.
Heather, Chris and I built a diffusion-type cloud chamber from items commonly available at Target. We used: - polycarbonate food storage container - block of dry ice - small baking tin - shallow plastic tray - 30 watt HID flashlight - some wire - 99% isopropanol - some paper towels - a power supply from an ionizer - a Canon HV20 HD camcorder and an HDMI TV as monitor/recorder - some black 3M gaffer's tape (NOT duct tape- that stuff is too shiny) - some bubble wrap to insulate the cold side beautiful - they were a source of Am-241 smoke detector (~ 1 microcurie) The results are quite good, and edited highlights will be shown here.
