The Aluminium Foil Boat Engineering Challenge
Objective: To build a foil boat that can hold as many pennies as possible without sinking.
Underneath the photographs you can discover about the science behind the challenge.
Science behind the experiment
There are two primary forces acting on this science experiment. The first force is gravity. Gravity is trying to pull the tin foil and pennies downward. The force of buoyancy is pushing the boat toward the surface.
The gravitational force is determined by the weight of the tin foil and the weight of the pennies in the boat. The force of buoyancy is the weight of the water displaced by the boat.
Your boat will continue to float as long as the force of buoyancy is greater than the force of gravity and you do not overload the boat so it will tip over or leak
