That little box uses special atmospheric conditions so that the alpha particles 'shooting' off of the mass of uranium force some water vapor in said box to condensate in their wake.
The streaks are, in a simple sense, the wakes left by the 'radioactivity' shooting off of that little rock.

There's so much to physics that you'll have to just accept that you'll never get that satisfying visualization of.
But when you do get one it's titties.

That is very interesting, thank you. One question, why the cold bottom? Isn't a warm top sufficient to make alcohol evaporate? Can you substitute dry ice with normal ice or Peltier cells?

The thing with this one is it's 100% harmless if you keep it outside your body, with regards to the radiation. Throw it hard enough and it can do some harm, I suppose...
