fluffy - 2015-07-06 Are all those particles cosmic rays? I was under the (possibly mistaken) belief that most of them were just background radiation from all sources, and the cosmic rays are differentiated as being the especially high-energy ones.
I also kind of want to do this because I want to watch my strontium calibration disc radiate outwards. Also I have a bunch of other things I could use dry ice for but not enough to justify buying a big block of it normally.
Stars for everything but especially the giant Ledenfrost fart (Ledenfart?) at 2:10.

She also mumbled an audible "oh please" at eyewear for isopropyl alcohol into a relatively contained space with a directional nozzle.
kingarthur - 2015-07-06 She explains that they are using the alcohol below the eye line and that since the eyewear does not make a seal and is basically just glorified glasses, it's next to useless.
Sputum - 2015-07-06 your girlfriend sounds really pleasant
