From the September 2007 issue

Would water released from a spacecraft into space boil because of the low pressure or freeze due to the low temperature?

Both. When released into space, water boils until it freezes. Space is cold, about –454° F (–270° C). Even though the water may be cool when released into space, it will boil immediately because of the nearly non-existent atmospheric pressure.
