All that work and they just melt it back down after!? Coulda sold that as merch/premium/art even if it’s totally unusable.

Kind of an older video but it’s still a goodie NileRed tried to recreate it on his other channel and really had a hard time nailing down the process, which goes to show how patient and talented Kiwami is at making knives out of random things.

Perfect for untraceable murder weapons, though. Almost as good as a frozen leg of lamb.

Especially if you’re looking to take down Superian. It’s his one weakness!

This is definitely going to be used to kill an anime villain.

nice art deco-ey crystals but overall this video brought to mind this:

I still need to do our bismuth crystal making exercise with the kiddo. Hopefully this summer

Seems to me bismuth is soft, like lead, and would make a really lousy knife.

But as an art project it shines.

hmm… bismuth particles in the air, bismuth bits in the food, bismuth in small punctures in the skin … and there’s Bismuth (atomic number 83) in the same period with Arsenic …no worries? well, semi-surprisingly it’s associated with a lot of "not known"s

Bismuthia is a rare dermatological condition that results from the prolonged use of bismuth. …Usually, bismuth produces a black line, due to bismuth sulfide, along the gums, near the teeth, similar to the Burton’s line which can be found in lead poisoning. This is not likely to occur if the gum is edentulous or the gum and the teeth normal. It is more common when gingivitis and carious teeth are present. Bismuth excess may cause stomatitis. On even rarer occasions, bismuth has been reported to cause pigmentation of the vagina and cervix.

All this worrying about Bismuth in the food has me worried, and is giving me indigestion.

I should go take some Pepto Bismol…

I love his ASMR-like presentation and sense of humor. No words, just little jokes that anyone can understand. Oh, and yes, the patience involved, almost for the sake of doing something the long way… well it’s nice when someone else is doing it, and it’s fast forwarded…

Buyer: “Bismuth be my lucky day!”
