1. All the materials must fit inside the dimensions of the box shown. Ice Keeper Contest Goal : To prepare an ice-keeping device which will allow for the least amount of melting within a 5-6 hour time frame. Rules 1. All the materials must fit inside the dimensions of the box shown. 2. No commercial products which are designed to insulate can be used. 3. All materials must start at room temperature at the beginning of the investigation. 4. Fabulous prizes will be awarded to those participants with the greatest percentage of solid water remaining.
