title: Effect of temperature on the life of soap bubbles, and their solidification at low temperature.
abstract: Soap bubbles (also films on wire frames) have been solidified at low temperatures. At~-30 degrees C the bubbles still behave normally, that is, they can be expanded by blowing air into them and contract when the air is let out. At ~ -80 degrees C they become glassy, have very little surface tension, and cannot be blown up any more. At ~-120 degrees C they become completely solid. No further change is observed by cooling them to 90 degrees or 77 degrees K.
