Why do soap bubbles float instead of sink? Is a slight breeze stronger than the force of gravity?
Always wondered...

Floating and sinking bubbles edu.rsc.org/experiments/floating-and-sinking-bubbles/827.article"In this experiment, students watch as bubbles of carbon dioxide – which sink in air – are created using dry ice. They then observe as hydrogen or methane is used to blow bubbles which float in air and can be ignited. Finally, mixtures of carbon dioxide and hydrogen can be used to blow bubbles which initially sink but eventually float."
