Buoyancy: How to best construct a boat out of a small square of aluminum foil.?
If given 1 square foot of foil, how do you best form the foil into a boat-like shape that will hold the most weight in it's hall when placed in water?

All I could find was this "The best designs are flat barges with small sides." http://www.nps.gov/miss/forteachers/brjralumboat.htm
I built two designs, that looked good, with 1 sqft of heavy duty foil. One was an Origamie Box whcih held 0.74 pounds. Two was a cone shaped whcih held 0.70 pounds.
