I let mine rest in warm water from the tap until they are thawed as well, but I put mine in a ziplock baggie so that they don't get wet and soggy. When they are thawed (water may have to be changed if it cools too quickly) I set them under a 100 watt heatbulb for 30 sec. (out of the bag on some paper towel) so that their heat signature is stronger. I then wiggle them about six inches from the snake's heat pits with the feeding tongs to trigger "feed mode". They usually take it after this.
