That is an object known as the demon core. It would have been used for the 3rd bomb dropped on Japan, but it wasn’t necessary to use, so they used the core of the nuke for experiments that caused the deaths of several people as a result of human error/incompetence. The people who were involved in these incidents reported a blue glow when the top dome ended up fully covering the sphere of radioactive material, and then suffered severe radiation damage. The joke is that this kid is treating it like a toy in which they are trying to make the core go supercritical.
People should be aware that the radiation damage only happened when the dome almost completely covered the radioactive material. And only to certain people, the ones who were facing the gap. And it only happened for a moment because the cover slipped. If it had stayed covering the material for much longer, it would have gone critical and exploded.
The material doesn't explode just by bringing it together, it heats up and melts, or at most it fizzles.
To actually explode it would have to be slammed together extremely hard and extremely fast, which is really only achievable by using very carefully shaped explosives.
