Hey, waitwhaaaat - thanks a bunch for the info. This was very cheap and easy to do! I had luck with the same ReliOn Thermometer, but the next model over- the 9 sec.flexible, water proof version for just a couple bucks more.. 9 bucks total I believe.. it was a little harder to jack than the standard ReliOn, but I just snipped the black and it silenced the speaker.. but the model I grabbed is SUPER fast. ...and while I was practicing, I accidentally dropped it in the water, and the waterproofing came in handy

Ultimately, I learned if you take your last digital temperature reading just as you leave your car to go into the lab, and you're running about 98 deg.. it's more than safe to just leave the digital in the car, crotch the bottle without the heaters and the temp is good to hold for more than enough time to test.. that was my experience anyway. For peace of mind though, just having the silent digital on hand can't be beat and the tip was really appreciated. Thanks
