I am guessing that it is God Emperor of Dune.
common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.

Molten salt in water.

Molten salt in water.



Is that from the quick and massive release of steam or a chemical reaction due to the sodium?

It's just thermal.

It's just thermal.

What's causing the delay there? It sits in the water for about a second, with nothing happening, and suddenly WHOOMPH!
Mooohn!

that's 5000 frames per second. "Time is an illusion. Lunch time doubly so."

We can see when the video slows down. That still doesn't explain why it falls into the water a ways before exploding.
The world is so exquisite with so much love and moral depth, that there is no reason to deceive ourselves with pretty stories for which there's little good evidence. Far better...is to look death in the eye and to be grateful every day for the brief but magnificent opportunity that life provides.

Probably the Leidenfrost Effect.
A novice was trying to fix a broken Lisp machine by turning the power off and on.
Knight, seeing what the student was doing, spoke sternly: “You cannot fix a machine by just power-cycling it with no understanding of what is going wrong.”
Knight turned the machine off and on.
The machine worked.

So pouring molten [anything else] into water would have the same explosive result?

No, I think there's a chemical reaction going on.

Watch the original video I posted above; he compares the reaction of sodium to this explosion, and they're very different. He concludes that it's a physical reaction, with water entering an indentation in the salt, becoming superheated, expanding and driving the salt bubble outwards, getting it into contact with more water, and so on.
Mooohn!

False. This ignores issues like capacitance, conductivity, and surface area. You can walk on hot coals without injury, but don't try it on a hibachi.
