Would a water balloon freeze in the atmosphere if you threw it out of a plane?

depends on how high you were when you threw it.

if it's above freezing on the ground and you go up in the plane to a point where it's below freezing, it's *possible* that it could freeze, if there's enough time while it freefalls for the appropriate amount of heat to transfer out of the liquid and for a phase transformation to occur.

here's where shit gets weird. if you were high enough above the earth (like 20 miles--near enough to space), the pressure up there is so small that it will actually cause exactly the opposite--the water could *boil*. Even though the water is colder at that altitude than the normal freezing point of water, in near vacuum, the freezing point of water actually decreases significantly. wrap your mind around that!
