Giant soap bubble - Dolores Park (San Francisco)
This is the guy that was making the giant bubbles, using a very simple set-up: two sticks with strings attached, soaked in mix of water, liquid dish soap, baking powder and corn starch (not sure exactly how baking powder and/or corn starch improves the quality of the bubbles). Some people also add glycerin.
