Sink or Float is a free online educational game that tests your understanding of buoyancy by asking you to predict whether real-world objects will sink or float when dropped into water. Each round presents you with a different object, and your job is simple: click sink or float before it hits the water. Get it right, earn points, and keep your streak alive.

What makes Sink or Float genuinely fun is how quickly it surprises you. Objects you'd expect to sink actually float, and vice versa – a rubber duck is obvious, but what about a grape or a raw egg? The game covers fruits, everyday items, and more, keeping each round fresh. There's no timer pressure, so younger players can think it through, while older players can challenge themselves to answer faster and build higher scores. It's the kind of game that feels simple but quietly teaches real science concepts.

Sink or Float is perfect for kids learning about physics, teachers looking for a classroom-friendly browser game, and parents wanting screen time that's actually educational. If you enjoy brain puzzle games, clicker games for kids, or educational arcade games online, this one fits right in.
