Yes, it is, if you are willing to put some effort into
your bubbles. Normally, a soap bubble blown in air will take whatever shape will combine
the largest interior volume and the smallest surface area. For a single bubble, that
would be a sphere. If you push two or more bubbles together, you will see that flat
areas form where they join. If your bubble cluster is large enough, some of the central
bubbles may become square.
Another way to create a single
square bubble is to build a cubic frame from pipe cleaners or drinking straws, dip it
into bubble solution, and you should be able to get a square bubble on the frame. It's
even possible to blow a second square bubble inside the first
one.
A third way to make square bubbles is by creating
"armored" bubbles. This is done by blowing an ordinary bubble, and then coating its
outer surface with a fine layer of extremely tiny (3 micrometer) styrene beads. The
beads supply an additional force to the bubble's exterior which changes the sum of the
net forces acting on the bubble, and a variety of shapes are possible, including
cubes.
