Program Information
Submarines are large, powerful vessels that travel underwater. First invented in the early 17th century, they have been used for military missions, tourism, scientific explorations, and more. The secret to submarines is buoyancy, their ability to float in water or air. The ballast tanks of a submarine fill with water to sink the submarine deep into the ocean, or they fill with air so the vessel rises to the surface and floats on water. In this program, participants create a simple submarine out of a plastic bottle to test the water and air ratios needed to achieve buoyancy. Participants can also develop hypotheses on what happens if you fill the water bottle with different liquids, or travel in salt water vs. fresh water.
Suggested runtime: 30–60 min.
