I walk into the vet room and find 6 keepers in the dark all staring at a blue bottle with the fluorescent light from our tortoise’s tank.

Whipping out my camera to catch the action before I even know what’s going on, I realize that they are all attempting to determine whether the water sample before them is reading positive or negative.

Every month we do water testing, and our wolf pool gets tested for e. coli.  The test is definitely hard to read (you are supposed to shine a fluorescent light from the bottom of the sample and no fluorescence= negative, while blue fluorescence= positive). Keep in mind this is already a chemically enhanced water sample of bright blue liquid.

Enjoy the below video, where we decide to compare the blue fluorescence to Marilyn’s newly blue striped head …

…to determine the results. Ok, scientists we are not.

Don’t miss Kent’s voice at the very end, it’s hilarious!
