as if in slow motion

Are all of these sentences correct:

[color=indigo]1-As if in slow motion, the wedding cake just crumpled in front of our eyes.
[color=red]2-The wedding cake, as if in slow motion, just crumpled in front of our eyes.
[color=blue]3-The wedding cake just crumpled in front of our eyes as if in slow motion.

If they are all correct is there any difference between their meanings?

Gratefully,

They’re all okay though I wouldn’t use the 2nd - I see no point in doing so when the other two sound more natural - no difference in meaning other than which phrase you wish to emphasise.
