I need to build a boat that contains only metalsNothing elseAnd the requirements is that it needs to hold fifty pennies inside the boat, floating in water, for at least ten seconds.I have recently built my boat out of aluminum foil, a lot of aluminum foil, and it has not been floatingAny help or suggestion?
An Aluminum foil boat should work if it is stable I would suggest that you get a container maybe a glass and with a single piece of Al foil put enough foil in so that you can form it to the shape of the glassThis won't look much like a boat but should float with the pennies inside If you know how much the pennies weigh you can calculate how much volume of displaced water will be needed to support the penniesVolume of a cylinder is pi R squared L use 1 gram of water per cc
