Now it might not be good to but I take mine out and for a few hours I leave mine in the sink with some cold water. Now it is not a good idea to leave it out all day when you go to work then you are asking for trouble
Use the water trick... like thawing a turkey. Put them in a 5 gallon bucket, fill full of cold water (add a weight to the top of they float), every 30 min. dump and refill, should thaw in about 3 hrs. You will need to use them right away.
