Never heard of this till today. Good thing they put this as a warning on all Microwaves..... They dont, that was sarcasim.

Hmmmmmmm, Hot RO/DI anyone >:D

They did it on mythbusters awhile back... soon as they stuck a spoon in it, it flash boiled.

We did this in science class in highschool, pretty awesome.

vacuums with water are always fun too

You guys are easily amused. Back when I was in Junior High, our science teacher took pure sodium and dropped it into water.

We did plenty of that aswell... Potassium better for you?

I prefer francium

thats cool

Cool

I prefer francium
I prefer not to play with radioactive materials... and good luck finding any...ever

lol... One day in undergrad i was going to the basic chemistry class, but there were cops everwhere and the building was roped off. They were cleaning out a very old chem storage area and found either Cesium or Rubidium and called the bomb squad for disposal.
In case anyone doesnt know, as you go down the elements on the periodic table they get more reactive in the family. (like sodium vs potassium). Anyways they store Cesium and Rubidium in sealed glass vials filled with oil. They are very reactive with ambient air and moisture. Hence the joke about Francium (at the bottom of the family) :)

I would think it was caesium... though radioactive... it is not as "rare" as francium... I have seen caesium before, I have never seen francium. I understood the "joke"

Could you imagine dropping that vial of cesium?

It wouldn't be good..., but the reaction would still be dependent on ambient temp and humidity. Bodies of water tend to have more violent reactions as they tend to trap or stall the release of hydrogen which doesn't mix with the metal when you have ignition or spark, so the explosions are more localized... the cesium in open air would have a reaction but it would not be explosive in most cases... The cesium would corrode almost instantly in open air... if the humidity was too high you could get ignition but it would not be explosive(or very little).

This should help some understand the effects ;)
Alkali metals in water, accurate! (http://www.youtube.com/watch?v=uixxJtJPVXk#)

That's a cool video. We used a much larger chunk of Sodium, and dropped it from a little higher, so it completely submerged.....shot up 15 or 20 feet in the air.

Here you go Wes, Last video and then I am done ;P

I kept waiting for him to break the vial open and pour it into water....

those were sweet ok who is doing this at a meeting
