Aluminum Foil Boat Contest Students are to construct a boat from a single sheet of aluminum foil that will hold more bb’s or pennies than anyone else’s boat. Each student or team will receive the same size sheet of aluminum foil and will be given a designated amount of time to construct a boat. Only the aluminum foil may be used. The boat may not be taped or glued in anyway. When the allotted time has passed, each boat will be tested by the instructor. Weights will be added until the boat begins to sink. Rather than count the bb’s, they should be dried and massed on a balance to determine the amount that the boat contained before sinking.
