Most hand manufacturing processes are stunning to watch, and in this case it apparently produces a product that is superior to mass manufactured competitors. It has to be way more expensive and time-consuming, though.
So pretty...so mesmerizing...so colorful...
This video was published by Adam Ragusea in November 2024 about a study from a month or so earlier than that.
The tl;dr of the study is that many black plastics are produced from recycled black plastics that are frequently sourced from electronic waste which contains higher amounts of particularly toxic, flame-retardant chemicals. Those 'new' black plastic items could - especially if used in high heat areas like food flippers and turners on the stovetop - release higher than safe amounts of those chemicals.
In the above video, Adam goes through the possible concerns that this raises as well as noting a possible math error in the study's calculations suggesting that the level of concern is slightly lower than the authors might have initially suggested.
The article was corrected - noting exactly the math error that Adam suggested, and Adam published a spectacular video explaining why that error should not undermine faith in the scientific process or even in the researchers and authors of the original article.

Glass is pretty awesome.
Here Dr Derek explores the history of glassmaking through modern glass like Gorilla Glass including how modern glass is made stronger, how it's tested, why glass is transparent for light, and lots more.
tl;dr - Yes, he can, but it's expensive and involves a whole lot of oxidation.
Damascus steel has a noteworthy pattern that is really what Alec is trying to reproduce with the titanium shown in these videos. Here he starts with alternating grades of titanium stacked then forge welds them together.
The steps required to then anneal and machine the titanium billet that he produces are labor-intensive to say the least.
But he does get some cool rings out of the process.
Parts 2 and 3 of the series are after the jump.
The widening gyre...
Yes, there's a garbage patch in the center-ish of the Pacific Ocean.
That garbage patch is not anything worth looking at, though. It's an area of higher than average concentration of plastic waste, but it's not something you could walk across or would have trouble boating through. Even a higher density area isn't necessarily a high density area.
As this video reveals, the most common photos attributed as being of the garbage patch are not of the garbage patch. They're of near-shore, highly polluted areas - which might actually be easier to clean up than the garbage patch would be - if we even should clean it up.
The video goes on to explore the sources of plastic pollution (hint - mostly not littering), the value of recycling (limited but worth doing), the role of big corporations in producing plastic waster (suck it, Coca Cola), the problems with microplastics (bad, very bad), and the need to reduce more than reuse and recycle.
These kinds of videos are way too easy to find on YouTube.
Plastics bad...we need to use less of them.
...and I write that as I sit beside of plastic bottle of Coke Zero Cherry that I'm drinking today.
