Lithium is the lightest metal. It is so light, it would float on water – if only it wouldn’t react so heavily with it. But Lithium can do much more: It works as a medicine against depression and can be found in many batteries.
Lithi the monster is a light-footed little fella, always playful and in a good mood. With its long thin legs it looks like a water strider.
