Mixing sodium and potassium is crazy (NaK)

For a while now, I've been wanting to make an explosive liquid metal, and all I need is some sodium and some potassium. And after mixing them together, I eventually had a perfect liquid metal ball. Finally, I pulled some of it out with a syringe, because there's just one thing I have to try.

Imagine trying to put salt on your banana and it just explodes

[@KSignalEingang]

The only thing wilder than the fact that these two highly reactive metals combine to form an explosive liquid alloy is that there was seriously a plan at some point to use it as nuclear reactor coolant.

[@CalebCalixFernandez]

It's amazing how two solid metals can combine to produce a liquid alloy. That's why I have always loved chemistry.

[@wart8106]

this guy knows how to make liquid metal really well

[@DaveDexterMusic]

when you think about it, "I decided to add a small amount of pure ethanol" is an all-purpose problem-solving technique that long predates modern chemistry

[@MrMikeT89]

This was among the most visually satisfying experiments I've seen on youtube. Especially when adding the ethanol causing the metals to combine

"I had a bunch of small and reactive metal balls"

The only guy that both can explain chemistry to us and seems like a 20 yr old college student

[@LifeLongMETALHead83]

You have a real NaK for making science fun. 😆

[@Bloated_Tony_Danza]

NaK was used in EBR-1 Mk.4 fuel elements. (Nuclear fuel rods) The liquid metal alloy helped conduct heat from the plutonium slugs to the uranium slugs and to the zirconium fuel rod cladding for a more even and efficient transfer of energy. There's a video on these fuel rods called "Fabrication of Plutonium" by Argonne National Labs. There's also a video on them handling these fuel rods after a partial melt down when the NaK escaped and caught fire.

The thing that caught me off guard was just how less dense sodium is. When he said 0.9 grams of sodium I was not expecting it to be this big of a chunk lol

[@ieshi23]

This sounds like a great idea, and surely can't result in any accidents

[@kushalchauhan5761]

To be honest i was bad at chemistry in school. But now that i see your videos, chemistry seems more interesting.

[@qubit1788]

The only thing more amazing than this is knowing that our brain literally uses this kind of reactivity of these two elements together on every sinapse.

[@Millie-eb3iz]

this is what I love about chemistry. You mix two really similar solid metals and somehow get a liquid alloy. So weird

Man im glad i found your channel, blowing my mind.

I worked on the fast reactor project until it's end in the early nineties measuring corrosion rates of boiler steels in high temperature liquid sodium. I was given a sample of NaK in the form of a paperweight by a colleague from Dounreay. Its contained in a phial under an argon atmosphere encased in clear epoxy. It's liquid at room temperature, its eutectic point. Pretty cool.
