About Sink or Float

In Sink or Float, you predict whether everyday objects will sink or plummet to the bottom when you drop them in water. You see a lineup of items—some heavy, some light, some surprisingly tricky—and tap your choice before dunking each one. Get it right and you score points; get it wrong and you learn why density and buoyancy matter.

The challenge ramps up as stranger objects appear: a rubber duck is obvious, but what about a sealed jar or a metal spoon? You'll sharpen your intuition for mass and volume with every round. Poki Games hosts this physics puzzler so you can test your scientific guessing skills anywhere, no lab coat required.
