...you thought someone was going to be able to get a critical amount of fissile material (originally plutonium) and bring it together using a machine???

I cannot possibly express how thankful I am that doing so is just about impossible for any layman.

Famously, they tried to recreate it once. And slipped. And people died

What about the title implies only laymen were involved? I had no idea going into it who would be doing what.

You thought nuclear security professionals were going to recreate an incredibly expensive nuclear disaster which killed a guy, except actuated by a machine with the humans at a safe distance? And that would have been more educational than just building a model of the thing with a painted foam core?
