This science experiment will bring out the curiosity and competitiveness in your residents. Begin by gathering the needed supplies: (straws, popsicle sticks, tin foil, a tub of water, and a couple handfuls of coins.)
Ask your residents to build their most buoyant boat out of the provided materials. Once made, they can place their boats in the tub of water and begin placing coins on top of their boats, one at a time. The boat that hold the most coins wins!
