You may notice the first half of these instructions are similar to the instructions for a working nuclear fusion device. After the first few dozen steps, be sure to press down firmly and fold quickly to overcome fusion pressure.

Huh, I've always thought that a black hole required a lot of mass, not just a lot of density. Apparently not true?

They can be any mass, it's density that matters. The smaller ones will not do much damage before they evaporate.

Hawinking radiation does a lot more damage the smaller a black hole gets
