Actually, we only assume that there was 2 grams of Caesium because they had previously used 2 grams of Rubidium- the amount of Caesium is not mentioned. As for Francium, it is an artificially created element, with a half-life of 22 minutes (if memory serves). That said, however, I'm sure it would be fun!

Well, the Interweb is a grand thing, and here's a little tidbit about Francium, turns out my memory was mostly correct...

"Francium occurs as a result of α disintegration of actinium. Francium is found in uranium minerals, and can be made artificially by bombarding thorium with protons. It is the most unstable of the first 101 elements. The longest lived isotope, 223Fr, a daughter of 227Ac, has a half-life of 22 minutes. This is the only isotope of francium occurring in nature, BUT AT MOST THERE IS ONLY 20-30 G OF THE ELEMENT PRESENT IN THE EARTH'S CRUST AT ANY ONE MOMENT (my emphasis). No weighable quantity of the element has been prepared or isolated".

So, in other words the biggest reason they can't have any Francium to blow up (real good), is that there is not enough Francium on the entire Earth to experiment with in the first place.

Interesting, thanks for that blankman. If I've learned anything, it's how to pronounce Francium. I always pronounced it like "France". I feel stupid, because Francium comes up in my conversations, like every day.
