Now to make pigs fly.....

Now to make pigs fly.....
Why not just strap the pig to a radio controlled ultralight? :o :-DD
-
Given sufficient thrust, pigs fly just fine!
It is however not a good idea to be underneath and it is somewhat tricky to tell where they are going to land.
Regards, Dan.

That explains it, I've been thrusting my pig all wrong.

Sounds like a project for Flite Test!

the Cops have had helicopters for years, of course pigs can fly. :P
Lighthouse lamps float on mercury baths, too, and they weigh a heck of a lot more than that anvil.

Inspired by the lighthouse bearing, apparently, some guy in 1986 came up with this puppy, a mercury bearing for your turntable. Not ideal for a house with small children... I mean, even less ideal than a normal turntable - at least they didn't poison the kids who crashed into it.

Hey, it's all perfectly safe, because there is an oil layer covering the mercury! ;)

That page also explains how the platter was centered, quite simply via the driving belt.
Thank you for posting the calendar clipping; I had not come across that technical marvel before. :)
-
Wow, that's a very clever turntable centering. :-+
I wonder why did they use mercury instead of some over liquid. A turntable doesn't need to be heavy, so it can be made to float on cheap, day to day liquids. If a heavy turntable is preferable for its big inertia, then they could have put more mass in the 4 rollers that guide the belt, and keep the turntable light in order to float on ordinary liquids like oil or water.

It would have been cool wacking the anvil with a 20 pound sledge too,
and see what happens :o
-
This fellow always struck me as not exactly happy to do this.

Can a gallium alloy be used as a safe alternative to mercury in those applications?
-
Good grief! Where do you get such a huge quantity of mercury? (and in such official, safety-marked packaging :palm: )
-
I'm impressed with the quantity, too.
First, it is very, very expensive, then (where I live) it is not legal to have large quantities of Hg without a permit.

Cody lives in Utah, the land of the free (despite mormons)... He has his families farm land to play on. His girlfriend is called Canyon. I'm somewhat jealous of his MAGA freedom and land ownership that includes a frikkin mine, but he has had youtube strikes and IIRC his Uni disavowed him too because he promotes science and not leftist politics.
-
Cool!
Here all underground resources (don't know how they are called properly) like mines, buried treasures or archaeology sites, whatever minerals/materials you find underground are all the property of the state/government, even if the mine is on your own land. Here, land property means you can plant seeds and harvest the crops, but you can not exploit the underground materials. If, for example, while cultivating the soil you discover some oil or other goods/values, those are not yours to exploit freely, those belong to the government (yet you might be entitled to some kind of reward/compensation for your findings, but you can not exploit/mine them by yourself). ^-^

What, floating anvils? :)
You do need to be a bit careful with materials compatibility (much as you do with Mercury, only a bit more so):

Considering the recent incidents with online services for independent creators not acting in the interest of the creators, we should encourage the use of P2P alternatives. As in he could use Bittorrent as a content distribution system and Bitcoin and/or Ethereum as a funding source, used in addition to what he already uses.

Yay! The Lockpicking Lawyer! Him and Bosnianbill are the two people that got me into my currently suspended hobby of lockpicking and even a bit of locksmithing.

Funny how combining two sexy things (an anvil and gallons of mercury) in an utterly predictable way, is still so cool.
I have an anvil too (80 Kg, 176 lb), but only about 300 ml of mercury. Cannot reproduce this demonstration.
Glad to see he did that in two nested containers.
Who else was waiting to see if he accidentally dropped the anvil into the tub?

More fun with Hg
