Whats the Science behind this:
Surface tension pulls in a way that minimizes the area with the soap membrane. This means it maximizes area insight the string without the membrane. Biggest area per given circumferences the string results in perfect circle.

The soap water on the outside of the string pulls towards the bubble frame and opens up the string loop. And because the soap pulls with the same strength everywhere, its forms a perfect circle.

I used Dawn soap to make my bubble solution. 

Make sure to dip string into the bubble solution before lightly dropping onto the bubble frame.
