Very nice but kinda complicated for the untrained mind to that stuff.. if curious check this too http://en.wikipedia.org/wiki/Radioactive_decay

If you happen to be in Berlin, visit the "Technikmuseum / Spektrum" to see a cloud chamber in live action!

she sounds like one hell of a date.
/barf.
can some one explain this to me, and act like im a 4 year old.
and use really short sentences.
and no long words.

we have one of these next door in the physics faculty at my uni in göttingen, GER. its a pretty old piece of equipment.

We are getting to watch the building blocks of our very reality in action and interaction with one another. How amazing, fascinating and utterly awesome! Thank you for this video.

Ok, I'm no expert but here goes: This chamber is filled with a substance which makes visible the natural decay of atoms. The last substance put in here(I think she first says radium, then says radon gas - you'd think she'd know) has a half-life of 55 seconds (making Radon correct), meaning that there is a reasonably frequent rate of decay. This is happening all of the time, we just can't see it.
This decay of radon can then lead to the temporary existence of Palladium 216, and with a half-life of only 0.14 seconds it fires again very quickly, creating the v-shapes. I'd guess that #14's uranium suggestion would be boring to watch as Uranium 235 has a half-life of 704 million years, meaning very rare fireworks.

I understood it, the knowledge is basic A-level physics but you do need a Physics degree to just be interested enough to listen to this woman's boring narration
