Does Polystyrene Blow Up In The Freezer?

Question

I have recently got a bottle of Polystyrene added water into it and shaken it up so now it is a sort of frothy liquid, I have transfered it to a plastic tub and wish to solidify it by putting it in the freezer, would it be safe to do so?

Thanks!

it shouldnt but in liquid form, it's safer not to put in freezer.  put ice cubes in ice coooler box nput it in the backyard and see how it goes.  leave a gap with the lid
