That YouTube channel is really great. Their older videos have a lot of lasers but they have expanded into many other subjects. I found them when searching about magnetohydrodynamics on YT. Highly recommended. I generally prefer consuming text but never have an issue sitting through their 30 minute long videos.

Recently they had a video about making very high performance thermal paste and were selling it, but three weeks later it still hasn't shipped and my email a week ago is unanswered. A shame, because their videos are still really great - I wanted to support them financially because the stuff they do is not cheap. But I guess selling a higher quality product for cheaper than the competitors isn't really a great monetization strategy. Meanwhile I had to settle for worse product at a higher price for my high power led project :(

Wow, thanks for turning me on to this guys channel. I like how he goes through the science in a way that’s accessible but doesn’t skimp or handwave.

Very nice video and approach to the problem

(the chocolate part start about 20min in but the candy part is definitely worth a watch as well)

This guy is the Walter White of chocolate.

Very pretty but the intro looks like syrup and not chocolate which is what this post is about. I know that your link promises chocolate later but that's no good here 8)
