Why do we see colors in bubbles?
Bubbles are created from a layer of water sandwiched between two layers of soap molecules, all surrounding a bubble of air. Light strikes the bubble at different places and is reflected from both the inside and outside surfaces of the bubble, creating unique and beautiful colors!
How cold does it have to be to freeze soap bubbles?
Technically, bubbles can freeze at any temperature below the freezing temperature of water (32 degrees F) but they don't last long. As soon as the water in a bubble freezes, the bubble starts to implode. The colder it is, the faster the water freezes, and the better chance you have to observe the frozen bubble before it pops.
How big can soap bubbles get?
Gary Pearlman set the world record for the largest outdoor free floating soap bubble in July 0f 2015. His bubble measured 3,399 cubic feet. That's big enough to fit 7,500 basketballs inside! Gary used two fishing poles with string tied between as his bubble wand. It took a lot of practice!
