Review on Clear Shot Glass - True Classic Design in One Size by John Floyd

I am writing in response to some comments. First off, this is a $3.49 item. Wash it and hand dry it in under a minute, and as a bonus, there's no leftover rinse aid to ruin your 18-year-old Scotch, a $300 bottle of cognac, or a single keg of bourbon. When you need an accurate measurement of a liquid, you have two options: weigh it, or get a good quality graduated cylinder. Remember to measure the bottom meniscus of the graduated cylinder. Water weighs about 39 grams per ounce. or about 1 ounce. per fluid ounce. They're close enough for anything but analytical purposes. The accuracy of the weight depends on the scale used and the measuring cylinder. I use mine to weigh my espresso beans, grind them and load the portafilter. This is how a $3.49 glass should be. You can use nail polish to draw lines over existing ones if they start to fade. Or a nail file to do small details I suppose. I immediately ordered a second one in case I dropped mine and broke it. It's a sturdy little wheel, but it's made of glass, not plastic.
