Old Uranium.png

Uranium is the chemical element of atomic number 92, a dense gray radioactive metal used as a fuel in nuclear reactors.



In the first game, the Uranium was indestructible, in a similar way to the Adamantium. Hazmat Workers will equip this object. When a Man steps on it, he will become a Mutant.

Super Scribblenauts

In later games, the Uranium has 1000 health points. It is an object that will automatically become glowing and will hurt objects around it. It will first simply hurt the objects. If objects get any closer, they will start glowing. Direct contact will kill people.

Hazmat Workers will make thisnonhazardous. It can be held, but will kill whoever holds it. Putting two radiations next to each other will cause an explosion. They explode when destroyed. They come out of Nuclear Reactors.
