A re-creation of the Slotin incident. The inside hemisphere with the thumb-hole next to the demonstrator's hand is beryllium (replacing the uranium tamper of the same size in a Fat Man bomb). There is an external larger metal sphere of aluminium under it (replacing the pusher sphere in this bomb's design). The plutonium "demon core" was inside the spheres at the time of the accident and is not visible, but its dimensions are comparable with the two small half-spheres shown resting nearby.
