Sink or Float

What happens when a rubber duck meets a bowling ball in the same tank of water? Sink or Float turns that curiosity into a guessing game rooted in real physics. Objects appear one by one, and you decide their fate before they hit the water's surface.

The challenge isn't always obvious. Dense metals and hollow plastics can surprise you, and the game leans into those moments of doubt. Getting it wrong teaches just as much as getting it right.

Beneath the simple premise is a genuine lesson in buoyancy, mass, and how water behaves with different materials. It's the kind of game that quietly builds scientific intuition without ever feeling like a classroom exercise.
