Plutonium
Once upon a time, scientists discovered a very special metal called plutonium. It is made when atoms of uranium are mixed and heated in a special place called a nuclear reactor. Plutonium is very special because it can split into smaller pieces and release a lot of energy.
But, plutonium is also very dangerous. If someone touches it, eats it or breathes it, it can hurt their body and make them very sick. That's why scientists and governments are very careful about how it is handled and stored.
It is also used to make bombs, which can cause a lot of damage if they are exploded. That's another reason why scientists and governments work very hard to make sure that plutonium is kept safe and only used for good things.
