Black Haired Girl Making Soap Bubbles Down By The Lake

Bubbles may take on other shapes when forced to have more sides, as within another shape. Typical bubble shapes demonstrated in bubble performances are the cube shaped bubble and the tetrahedron (triangular shape with 4 sides) bubble. When all of the outsides of each shape are filled with bubble solution, a bubble may be formed inside to mimic the shape.
Freezing
Soap bubbles blown into air that is below a temperature of −15 °C (5 °F) will freeze when they touch a surface. The air inside will gradually diffuse out, causing the bubble to crumble under its own weight.
