Super Slush Powder

This powder will turn water or other liquids into a solid instantly

Can be used for a variety of effects, simply add a spoonful to a glass of water and watch it turn to a solid.

A classic routine would involve the slush powder and a mirror glass. Add a spoonful to a glass of wine (or coloured water), making a magical gesture, turn the glass over and the wine has disappeared to be replaced with a silk!
