Slush powder is a very useful magic accessory that allows to perform stunning effects. In fact, if you add to a glass of water a spoonful of this powder, you will see the water instantly become solid! An ideal combination is, for example, to use slush powder with a mirror glass with which you can perform a “classic” routine: the magician fills the glass with wine (or colored water), makes a magical gesture and turns the glass over… the wine not only vanishes, but instantly changes into a red silk.
