When you blow through a bubble wand, the soapy water traps air. The soap and water molecules pull together using a force called surface tension. This force causes the soap film to shrink as much as the air trapped inside allows. A round shape, or sphere, is the shape that holds the most air with the least surface. That’s why bubbles are round! There are no corners, no wasted effort – just simple science making a fun, floating ball for kids to enjoy.
