Field-expedient cloud chamber:And then I saw this story; it turns out that when you rip off sticky tape (that's a scientific term) in a vacuum, there is a discharge of static electricity, so electrons are transferred from one side to the other, and when they strike the tape, they slow down. Energy is of course conserved, so it has to go somewhere, and somewhere in this case is a astonishingly powerful burst of X-rays. This is yer bremsstrahlung, right?
- shot glass.
- High-proof vodka
- Rubber balloon
- Rubber band
- Dry ice
- Light source
Pour a shot of vodka. Drink it. Do not wipe out glass. Put rubber balloon tightly across mouth of glass, fixing it in place with rubber band. Set glass on block of dry ice. Shine light through side. Pull up on rubber sheet to lower pressure in the shot glass. Observe tracks in the cloud.
You can probably see where I'm going with this. Now, who sells dry ice in London N19? The spirit, obviously, is no problem. Need to think of a way of arranging to peel off the tape under a vacuum, though.
Hey, it's significantly less crazy than freeze-distilling H2O2, or doing the same thing to Timothy Taylor's Landlord Ale. (You know who you are.)
