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 mediums and the large can exceed the limit with dense contents. Perhaps the title could be changed to omit "physical" and add back "small"?

I once purchased lead weights online, and they came packed tessellated in a flat rate box. Shipper definitely got their money’s worth.

Out of curiosity, what kind of weights were they? I was under the impression that it has been phased out of many uses because of high toxicity (including via skin absorption when handling it)

Semi related - a few months ago, while not fully sober, I was aimlessly browsing through Amazon and ended up owning a set of two 1.5inch cubes - one aluminium, one tungsten.

It’s kind of a silly purchase considering it’s a lot of money for 2 metal cubes, but it’s honestly very impressive just how heavy that small cube is - both objectively, and when compared to the aluminium cube. Also makes for a great talking point when having guests over.

Exactly what I was thinking. Bet they're iron, about 70% less dense and a good supplement for your blood cells. https://www.wolframalpha.com/input?i=densiy+of+iron%2Fdensit...

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.
