Lol.
Cute/funny.
EDIT: I'm pea roasting this because all day long I have not been able to get the song out of my head. I love that video, even though it's not very "nostalgic" for me, since at the time I was in the Care Bears/My Little Ponies/Stawberry Shortcake age group.

I've done that
but cesium is cooler, I've only seen a video of that, and it broke the beaker

it is
if you went one more down the row, to radium I think, it'd be both violent and radioactive :)

I thought cesium was radioactive
Didn't they use it in the atomic clocks?

they do
but it isn't radioactive
the official definition of a second is a certain number of vibrations of a cesium atom when held at a certain temperature, so they just measure that. Atomic doesn't necessarily mean radioactive :)

I haven't watched these yet
but these should be interesting, probably from the same video I saw in chemistry class
