	@rmo134 you still shouldn't put them in water.

	@rmo134: Yes, the Brainiac video was faked. However, rubidium and caesium do react explosively with water, as demonstrated by the following video from the Open University (Rb at 1:55, Cs at 2:10): http://openlearn.open.ac.uk/mod/resource/view.php?id=294420 The other videos on that page are also well worth watching. Quote of the day: `You can see that things become gradually more terrifying as we go down the group.'

	I really think Kalium should be accepted for Potassium..

	@Levente: The only name for the element in English is potassium.

	the problem with mythbusters whas that there piece of metal consisted of several solid chuncks (and was coated in an oil). this greatly reduces chemical interaction and therefore the bang.

	is it worrying that the first ones i thought of were caesium and francium???

	Love the fact that the advert I had on the page was for a Cesium, Rubidium and Lithium manufacturer!

	Stamps:	Nov 7th, 2010 at 17:55 GMT		2 points
	I don't know why but I always spell Cesium "Caesium"

	Ejd32:	Jan 16th, 2011 at 14:57 GMT		2 points
	Stamps: You are right, the official spelling is caesium but on most periodic tables it is under cesium, but it still has Cs to represent it!

	Caesium! Caesium! Caesium!

	@yorickved 1. The Mythbusters team go to great lengths to ensure that what they're doing accurately recreates the claim. The Brainiac video was faked. The reactions aren't as big as they made them out to be. 2. Was. They're. Chunks. @Stamps While caesium and cesium are both accepted spellings of that element, Aluminum is a little different. Aluminium is the British spelling, while we take out the last "i" in the US.

	It would be extremely entertaining to see a francium-water reaction, but it would be impossible to have this happen. Francium is so fiercely radioactive that it evaporates itself from the emitted heat. But as Theodore Grey says, "Boy, would you have some fun with it!"
