Holy Sh*t. He has a CO2 fire extinguisher! If he where to actually use that against a cesium fire it would EXPLODE. Cesium even reacts with CO2. You would NEED a Lith-x/graphite extinguisher. Always remember if working with Alkali metals to have a Class D fire extinguisher!
Or at least put a video of the resulting explosion on youtube so we can all be entertained by your stupidity.
I was thinking about it, when the guy said "Cesium loses its electron and becomes Cesium +" I was wondering what exactly happens to the water, and whether H+ and/or OH- become present... I couldnt figure it out, and then you explained it :) Awesome
I did a rough calculation and it seems to me that 5 gram caesium will produce only about 1.7 liters of hydrogen (at normal pressure and temperature). This might explain the smallish explosion.
for those that are confused or disappointed by the size of the explosion i recommend watching thunderfoots's "Brainiac's alkali metals were FAKED!" video.
but still, 5 grams of caesium i remember about a couple drops could make a really big bang i was a little disapointed with the reaction but i still liked it
both ceasium has the ability to spontaniously change polarity and fire neutinos and the closes living organism each time this occurs the polarity of one of the neutrons in the neucleous is changed and the entire nucleuos is reformed thus it can be a cation or anion, however if bonded with carbon tetrafluride it will reabsorb the neutrinos and spontaniously combust and end the universe and the time vortex in doctor who will collapse and cake as we know it will cease to exist.
Could you do drop caesium in water in a nitrogen or argon atmosphere, I'd like to see if the caesium will still explode. I think it happens because the reaction causes caesium to boil.
@CitrineVlogging Francium exists for an extremely short time as it is radioactive. Only a very few atoms of Francium has been synthesised in the lab at any one time. You will never see a video for francium's reaction with water in the near future.
It is the radioactive decay of the isotope Cesium-133 that defines the length of a second; since 1967, one second has been defined as 9,192,631,770 periods of radiation corresponding to the transition between the two hyperfine levels of Cs-133's ground state. These periods always stay the same, and so this isotope is used to make atomic clocks. Natural astronomical cycles were no longer deemed acceptable for this purpose, because the length of a day on Earth is very slowly increasing.
This setup has oil covering the Cs surface, minimizing the reaction surface. You really should have stored Cs with N2 with no oil, and then drop the Cs into water.
@1997xander all that smoke is coming from the nukes, is the reaction of water and fuel!! its the same reaction but slower, but the theory makes it clear in some way, and high levels of cesium find in Tokyo carfilters.
I'm curious as to what would have happened if you were to put molten caesium into the water. It would give the metal even more surface area to react even quicker with the water, wouldn't it? Awesome video though!
"I don't know if you ever thought about it, but you could define one second as a fraction of a day..."
"I don't know if you've ever tuned a radio... but as you turn the knob, sometimes you don't have to be very precise [...] but sometimes you have to place it very accurately to get the station you want."
Listen guy... I know I'm not you, but I'm not a complete dumbass!

@VoltOptConstruct LOL i'm not to good at science but i think that the acid removes the electron in cesium faster and that creates a stronger reaction. that was just a guess i only know it reacts more is because at school our teacher done rubidium in water, then in acid and it was crazy in acid.
@racoon965 Well water is an acid, i.e. it is a proton donor. Stronger acids than water donate protons more readily and that's why the reaction would occur faster, not because the outer electron in Cs is any easier to remove.
Everyone always gets excited when cesium or rubidium are tossed into water. Even though it is counter-intuitive, the reaction with water and potassium can be much more spectacular given enough potassium. The "bang"-factor is determined by how well the hydrogen mixes with air before it ignites, not by how fast the metal reacts with the water. It is all detailed on this one website by theodore gray, but comments doesn't allow links. Plz make a vid where you toss a block of K in a lake :).
@kevinzki21 There's only 20-30 grams of Francium that exist in the Earth's crust at any given time. We can only guess how big the reaction is based on what we know about it's chemical and atomic makeup.
@JayseWeaver francium will not be as violent with water as cesium due to some quantum mechanical effects making the probability of finding its electrons closer to the core higher rather than further away as we would expect. and therefor be less reactive, since the energy required to remove its electron would be higher than we would expect.
