Colourful helium balloons float upward following buoyancy physics. Pop them with a click for satisfying confetti explosions, or play the colour-hunt game to pop balloons of matching colours.
Buoyancy forces, air resistance and simple wind physics. Each balloon rises at a rate determined by its size and helium volume.
Click to pop balloons. Use sliders to adjust wind and balloon count. Switch between free float, pop mode and colour-hunt game.
Real helium balloons rise because helium is about 7× lighter than air, creating a net upward buoyancy force of roughly 1 gram of lift per litre of helium.
