Couldn't read the Twitter post with NoScript, and didn't want to turn it off, but I verified the claim. Forgive me for working in cubic inches, but those are the unit measures specified on the USPS web page: https://store.usps.com/store/product/shipping-supplies/prior... So the volume of the box is 82.6669921875 cubic inches. Assuming we're shipping a block of Tungsten at 0.7 lb/in^3, then our shipment would weigh 57…
Since I discovered the availability of anvils on Amazon, I have always wondered about the economics of shipping them. Right now, I can order a 66lb "Happybuy" anvil for $153 with free prime shipping. One assumes that the $153 includes the cost of shipping it all the way from China in the first place. For comparison, a similarly sized anvil from a reputable local dealer costs $949 plus tax and shipping at the lowest r…

FYI next time you can use something like nitter (eg. https://nitter.net/PaulMSherman/status/1516936733769801734) which works with scripts disabled.

When I heard that the crypto millionaires were buying Tungsten cubes for fun, I checked into the prices. Amazon lists a 1.5" cube (weighs 1 kg) at $199 and a 4" cube (that weighs 18.9 kg [0]) at $3499. There's no way I'm spending that, but I will admit to wanting to experience their density for myself.

I have a part off an aircraft (nobody seems to know what part or what aircraft). I imagine it's partially tungsten since it's not much bigger than a 4x4 cube and has to weigh close to 50lbs.
Tracking down obscure stuff like this is soothing :)

Thanks for that tip. I am about to ship an implosion-type nuclear device and my first thought was if I could use a USPS flat rate box.
Be careful, the shipping rules are tricky. For example, you need to compress the implosion-type nuclear device with another implosion-type nuclear device first to get it to fit in the box.

« It is physically impossible to exceed the 70-pound domestic weight limit for a small flat rate box. The interior dimensions (8 5/8" x 5 3/8" x 1 5/8") are ~75.333 in^3. If you filled the box with pure osmium, the densest substance known to man, it would weigh ~61.48 lbs.»
Followup Tweets: Should have said densest substance on Earth. Fill it with neutron star and you’ll be approx. 30 trillion kg overweight. Had to post this correction before @neiltyson popped in with an "Actually..." I don't have anything to plug, so just try to be a little bit better than normal if you happen to think of it, but don't make a big deal out of it--no one's asking you to be a saint.
While the tweet is correct ("It is physically impossible to exceed the 70-pound domestic weight limit for a small flat rate box") the shortened title here which omits the word "small" is very misleading. The USPS offers a variety of sizes of flat rate boxes ( https://www.usps.com/ship/priority-mail.htm#flatrate ), all of which have the same 70 lb weight limit. It's only the "small" that cannot be overweight. The two…
Ok, we've removed the (redundant, I suppose) word 'physically' and squeezed in 'small' in the title above.
I played around with the title and character limit for a minute, and managed to get: "A small flat-rate USPS box's weight limit is physically impossible to exceed". How's that?
These are amazing for shipping bullets. Not loaded, but for reloading. My mailman hates me but they keep the costs down.

That's a great question. There's solid phases you can create at extreme pressure that remain stable or metastable at STP, like the diamond allotrope of carbon. I don't know of any examples that retain a high density at low pressure. Is it possible for something like that to exist? There was a suggestion that hydrogen metal could be metastable at low pressure -- it would be much denser than molecular hydrogen -- but i…
Diamonds are a great example!
What many may not realize is that there's a thriving industry in sending passengers on planes for the sole purpose of them taking things from A to B. Years ago, you could get discounted flights to Europe where you couldn't check in any luggage. Why? That allowance was taken up by documents for various clients. This was usually quicker than any courier services at the time. I've had friends who worked in the oil and g…
My close relative worked off shore for decades. Sometimes a down large production platform is a MILLION dollars an hour. Flying someone anywhere with a $250,000 part in their hands is nothing. There are entire industries built around "getting things to the rig/platform" faster.
