Re: O/T Have a little fun in the cold weather
here's something to try:
Soap bubble skin is made up of two layers of soap molecules surrounding a layer of water molecules. Since temperatures of 10°F and lower are below the freezing point of water, the thin layer of water in the bubble skin freezes quickly before the bubble has a chance to burst.
Bubbles that are made by drawing a wand through cold air freeze almost instantly but bubbles blown by mouth contain warm air. When blown bubbles meet cold air, the warm air inside the bubble contracts as it cools causing the skin to wrinkle. The soap film adds strength to the frozen layer of water within the bubble wall. Because the bubbles freeze quickly, they will be small.
