Actually a rock would drastically lower thermal mass if you have 
access to freezing temperature in the frig.  Change of state requires 
much more heat than just raising the temperature. You could freeze 
plastic bags partially filled with water with good effect. But you 
take a chance that they will leak into the film especially after 
reusing them a while.  In that case plastic bag everything. The blue 
ice pack things are just less messy.
