Needed: 1 ice cube tray 1 piece of paper Water Sugar
Put the name or names in a blue ice tray (I'm sure the color of ice tray is insignificant) in
each cubicle, if you have their signature that would be even better.
Fill the tray with water and put in freezer (this prevents them from taking any
energy against/towards you.) If you want to sweeten them up add sugar or honey to water.
