The document describes a prototype boat made of a plastic bowl, balloon, aluminum foil, and paper cup. The balloon is taped inside the bowl and surrounded by aluminum foil to displace water and prevent leaks. A paper cup attached to the center of the balloon via tape is used to hold weights. The blueprint details the dimensions of each component. The purpose is to create a boat that can hold weight without becoming unbalanced, using a balloon for buoyancy and other materials for structure and to hold weight. Test results show the boat tipped over with more than 14.25g of weight on average due to uneven waterlogging.
