A heavy ship can float!
Ships are made of heavy metal… so how do they stay on top of the water?
Here is a metal ball and a metal boat — same metal!
tight ball
wide boat
Water always pushes UP on things!
Tap to squish the metal — ball, then boat!
Tap the metal — watch it change shape.
Same metal, two shapes — we drop them BOTH. Which one FLOATS: the ball or the boat?
Tap your guess!
