I know that temp guns are the best...but I just knocked my only one into the cats water bowl. I have ordered a new one but it won't ship for a while (and then it will take a few days to ship). To make things worse, I have been in the process of figuring out the basking spot with a new light so I have no idea what the proper basking setup looks like (with that particular bulb)! Any other good ways to measure basking temps until the temp gun arrives? I really need to know!
