But it was powerful.
Does that mean it was the size of a house?
I heard that NK’s NUK Test was 5, or so, times the one set off at Hiroshima!
It only take 5-10 lbs. of U-235 to make a massive bomb!
And U-235 is made from centrifuges, starting with ‘Yellow Cake’ (normal uranium found in the ground).
Remember Einstein’s equation: E = MC2
Put in 5 lb of U-235 times the speed of light squared!
That’s a massive amount of energy!
