Hey... What The Fuck???

Hey... what the fuck???

So I read the article, and this is super cool. Basically what happened is that they let a drop of butyl alcohol out from a syringe onto the surface of another liquid, and it just... hung out there? For a very significant amount of time, too. In the past, this type of "droplet levitation" has only lasted a few milliseconds max, but this droplet was staying levitated without any external forces applied for tens of minutes.

The reason this happens is because of Solutocapilllary convection, which as far as I can tell essentially boosts the surface tension of that one spot in the underlying liquid using vapor molecules, so that the butyl alcohol molecule can't sink in.

Also, the reason why I specified that the reason this was cool is because it was done without external forces is that APPARENTLY we've been able to levitate things using sound waves since like... the 1930s. And it makes sense that you can do that, in principle, but it still looks absolutely wild to see.

To All My Black Followers And Friends, Stay Safe.

To all my black followers and friends, stay safe.

Also, I would like to add that black lives have always mattered, will always matter.

It’s awful that we even have to say that because it should be a given. However, we need to say it loud and clear for the racists.

We cannot be silent.

Bought my uncle a burger and milkshake in exchange for letting me disrupt the holiest day of the week, NFL Sunday Football, so I could install a Pi-hole and free the household of ads...the thing abt the specific boomers I live with is they told me not to trust people on the Internet but they do not understand the algorithm or online advertising and think that Facebook has their best interests at heart. And every time I have tried to explain to them that no, blorbo from my dashboard is not selling my kidneys on the dark web but Google from your capitalism is definitely selling your web searches to every advertising company on the planet, they think I am paranoid. How could their personal friend Mark Zuckerberg want anything bad to happen to them etc. I am fighting battles I did not know existed!!!
