Under pressure, the freezing point of water is lowered so it can stay liquid below 32degs F (0degC). When you release the pressure in the can, the freezing point becomes higher.
For example, if the soda is at 29 degs F, the freezing point under pressure may be 20 degs F. But when you open it, the freezing point returns to about 32 degs F and the 29 degs F liquid freezes.

When the gas dissolved in the liquid is released and expands, heat energy is removed from the liquid with the escaping gas and the liquid cools further to its freezing point.

because it would freeze in the fridge, but because the ice takes up more space then the liquid(and it has a limited space being in a can and all) when allowed to have more space(opening it up) allows it to freeze
