Hey that's a good idea. Where do you buy those these days. I use to use them on the job in my lab. I had to write client information on cold wet plastic water bottles that I had just removed from a huge walk in refrigeration. We did water sampling and stored the water samples in plastic bottles. I had to log each bottle or sample into the main computer systems and assign it a lab number. But try writing on a wet plastic Nalgene bottle with a marker that won't write when the tip gets wet. LOL

Grease pencil should do the trick even on wet plastic surface.

Thanks for tip. I am heading out to Wal-mart to get some film developed so I'll see if I can find one


And also about the Line and it breaking when using a palomar knot. I wonder if that line was old or had been exposed to a lot of sunlight? There is so much air pollution in this area these days that the OZONE really does a number on plastics and that includes our fishing lines. I saw a show yesterday on TV where the tire manufactures put special pellets into the dry mix used to make new tires. Those special pellets were added to the mix to make the rubber immune to OZONE attack. They spend a lot of money adding that stuff into the mix that is used to make the rubber for the tires. In fact when I first started working in the air pollution field I read that the test used for detecting the amount of ozone in the are back in the old days. (Pre 1977) was to take a piece of rubber and bend it and put out where it was exposed to the our side air. They would see how long it took for the rubber to crack. They measure the time in hours and days before this occurred. The sooner the rubber cracked the more ozone was in the air. If it took longer to crack the rubber then there was less ozone in the air. I got a big kick out of that when I read it. We used an Beckman Ozone Analyser that cost over $10,000 and it actually measured the amount of air taken into the machine with a critical orifice and then reacted any ozone in the air sample with Ethylene gas to produce light emissions which were detected by a photomultiplier tube and sent to a amplifier circuit and then onto a graph recorder. These days the signals are read ever second and digitized and then the concentrations and hourly ozone readings are performed with a desktop computer. The results are sent over the phone lines to a central office for compilation and reporting.
