Just like all alkali metals rubidium reacts vigorously with water.
Turns flames into deep red – popular with fireworks. Besides that it’s mostly used for scientific purposes.
Ruby the monster is a real chatterbox. If you meet her, she rambles on with no mercy. She loves everything that’s red: Poppy flowers, lipstick, sunsets and of course red fire works.
