There's a chemical reaction going on inside the glow stick which makes
the light. If you put the glow stick inside the freezer, the reaction
goes more slowly (most reactions do this), but it will still be going
forward, and so the glow stick wouldn't recharge.
(The reaction starts once you shake the glow stick and make two substances
inside the stick combine.)
It will last longer if you put it in the freezer, but it won't go
backwards. You'd need to un-do the chemical reaction, and I don't think
this is one of those easily reversible reactions.
