Do you think rubbing Vaseline on the bottom of an aluminum foil boat will help it stay up longer? - holding pennies in aluminum boat
For the physics course I have a boat do not exceed 100 square inches of the film. I must have more than 25 cents to get the touch to get above 40, an A. Put Vaseline on the underside of the vessel (the part that touches the water) to help in any way? The idea came to me, because I think it will help them, not better on the surfaces.

The shape of the boat is what is important to get it.
You can help to prevent leaks through cracks in the film, but makes the boat heavier. Petroleum jelly is mixed with water, so I'm not sure what you mean by sticking with water. Experiment to determine weaknesses in their designs, and use this knowledge to achieve better designs.
You can calculate the quantity of water are required to move the boat.
When the fleet of vaseline, maybe. But what do you mean by "stick" to the surface of the water? In any case, it will break the surface tension of water.
No, not stick, a long tape, glue and try to chew gum (your suggestion, I take no responsibility for their actions).
