any suggestions on how to make it?
Is it one of those kinds that has to hold pennies? If so, the best design for an aluminum foil boat would be to try to make it cover as much area as possiblealthough you still want edges to hold the pennies, you want to try to cover as much space as possibleAlso if your trying to design a small aluminum foil boat try to make a sphere shaped boat Maximizing a boat's load carrying capacity, IS a function of maximizing its volume below the surfaceBUT, if it floats, you can add the open to air area to your material surface area as wellFree surface area! Yeah! Increasing the available area, increases the volumeSo, a half sphere is best What about construction rules? What considerations regarding cutting, taping, gluing, or brazing are involved? If you are given a single piece of foil and can only fold it or manipulate it, then a dish shape would be bestThe dish shape will conserve the most area/volume for displacement, as it will minimize the amount of area lost due to folds, and maximizes that free open to air area Take a ball point pen and score short lines near the outside edge all around the foil (without tearing it of course)These lines should be parallel with lines that radiate from the center outThis should have the effect of creating a lip around the outside edgeStack the cargo at the center and move outward as the boat starts to become unstableI wonder, however, if there might be some creative way of trapping air beneath the boat to get some more free open to air area (like an egg carton)There might be some total gainAlthough it does not seem intuitively possible, the trapped air WOULD displace volumeI think the best possibility would be a rolled over lip on the edgeIf the foil was stiff enough to prevent deflection/deformation, I think it would work carbon fiber.
For one atomic molecules like Helium molecular mass equals atomic massFor 2 atomic molecules like H2 you have to double atomic mass in order to count molecular massFor Complex molecules you should count atomic mass for each element and then add them up! hope to be useful
