Why are bubbles round?
A bubble is air wrapped in a super thin skin of soapy water.
Pip’s answer
- A bubble is air wrapped in a super thin skin of soapy water.
- The skin squeezes in the same amount everywhere, like a gentle hug!
- When something squeezes evenly all over, it makes a ball. So bubbles are round, buddy!
For grown-ups
A soap bubble is a thin film of soapy water surrounding air. Surface tension pulls the film inward evenly in every direction, and a sphere is the shape that encloses the most air with the least surface. Bubbles may wobble while floating, but they settle back into a ball.
Ask your child: Can a bubble wand shaped like a square make a square bubble?
