The Science Behind It:
A cube-shaped frame made from black-polka-dotted straws, secured with red pipe cleaners, contains a clear soap bubble, with a straw extending from one corner.
When a bubble forms inside a cube-shaped mould, it's constrained by the mould's shape. The bubble adapts to the corners and edges of the mould, forming a cube-like shape. Once it loses the constraint of the frame, the bubble will either burst or return to a spherical shape.
Think about it: besides cube bubbles, what other shapes of bubbles can you create?
