Why canned soda usually doesn't explode when cracked open but bottled soda does more frequently?
I've never even had it happen to me and ive opened thousands of soda cans in my life. all it does is make a hiss and release some air but nothing ever spews out.
How come it happens with bottled soda much more frequently? I always have to be careful when opening bottled soda because it bubbles up rapidly and quickly if im not careful?
I meant plastic bottles. not glass.
so flexible like aluminum cans.

1 - bottles are typically much larger
and (so) have much more gas that can be released
a little bottle shaking (by which I mean: unintentional vibrations)
releases much more dissolved gas
than does a little can shaking
just because there is so much more gas that can be released.
Note: if it is true that larger bottles tend to "erupt" more often than small bottles, then that is probably the correct reason.
2 - bottles are transparent or translucent
and the light that reaches the soda
tends to release the gas dissolved in the soda
compared to the (opaque) cans which allow no such light to affect the soda

JUST a guess ... cans have a bit of flexibility and can expand a bit so the pressure inside the can is reduced. Glass doesn't expand, so the contents will be under more pressure. But at the same time, you would expect the carbonation in soda to last longer with bottled pop than with canned pop. Never checked it out though, so this is just an educated guess.

snap your fingernail against the can/bottle, two or three times, before opening. doing so … causes the air-bubbles on side of vessel to release.
