You threw me off with the "do yourself a favor" part. That can have different connotations. I was familiar with a lot of the topics since I do a lot of reading on science and tech. I did watch the ones on coffee makers and tantalum. Did you know that nutmeg has small amounts of a powerful hallucinogen called scopalamine - the same active ingredient in Dramamine? Prisoners would sometimes try to steal enough to get high on but apparently it's an extremely unpleasant high.
I really liked the coffee maker one. I understand in principle how it works, but it still seems like magic.
I'll bookmark it and try to come back to that channel sometime. I also subscribed.
