Master of How cruise ships work
Ch 1 · The magic of buoyancy
construyendopaz13 Trace different ship hulls to learn how water displacement keeps giant cruise ships afloat.
futura Cruise Ship Buoyancy
A giant ship, though it weighs a ton, Displaces water, so it floats along!
futura Cruise ships use displacement hulls designed to push water aside rather than ride on top of it.
testingarti Compare the ship's towering deck to the iceberg's surprisingly small visible tip.

futura Explore the magic of buoyancy in this fun, toy-like cruise ship game. Discover the science behind how massive ships stay afloat.
Fun Fact
Archimedes' bathtub moment: The ancient Greek scientist Archimedes discovered buoyancy principles around 250 BCE while taking a bath.
Glossary
buoyancy (noun)
The ability or tendency of an object to float in water or other fluids. Ancient Greek mathematician Archimedes first formulated this principle, which enables modern steel cruise vessels to remain afloat.
