When we opened a cold bottle of club soda, ice immediately formed inside.  
Research showed that water freezes more easily when the pressure is low, so I 
thought the opened bottle = lower pressure = ice able to form.  But this did 
not happen when I opened a cold can of soda (same refrigerator and temperature).
