Flowerball

The Flowerball was a children's toy invented by Leonardo da Vinci. Sound activated, a clap of one's hands would cause the sphere to open and a bunch of flowers would pop out.

Creation
Having taken the designs from the Notebook, Piero de' Medici and Valerio tricked Leonardo into designing it so that could the design to create a fireball for the Mechanical Man. The Flowerball was presented to the Duke of Florence as a birthday gift but Leo mistakenly believed it to be the Fireball, leading to him being publicly shamed after accusing Piero of an assassination attempt.
