They also used a distillation setup under vacuum to collect the cesium gas and condense back to liquid. It is probably the same for other alkali metals and earth metals. The salts are a cheaper source for the element.

[@firefly618]

Some of these reactions start very slowly, showing little to no effect for several seconds after contact, and then explode in less than a millisecond. To me this is a great display of the explosive power of the exponential function. Even when the base is only slightly above 1, you only get a limited time before the function explodes. (Try plotting y=1.001^x in something like Desmos and then zoom out until you see anything happen.)

[@deltab9768]

I think part of why it reacts so violently in water (more than potassium, for example) is because of its actual reactivity, but part of it is it’s dense enough to sink below the surface before bursting. That means that instead of blowing up into the air it blows into more water completing the reaction.

[@YuPuWang]

And another part of the explosiveness comes from cesium’s low melting point, turning into a liquid with minimal heating from room temperature. The said liquid then gets its electrons ripped off by H2O and causes a Coulomb explosion where bits of positively charged alkali metal particles violently repel one another. This is exactly the reason why NaK explodes like cesium does, sodium produces delayed explosions (if it does explode at all), and lithium simply does not explode when thrown into water.

[@lordroo8484]

But the effect is quite different if compared to a Na/K alloy.
