This CFL Secchi Pint Glass is What You Want for Christmas

We don’t know about you, but these last few days before Christmas are the prime time to scramble for last-second gifts. So, really, let us just say “You’re Welcome” for lifting that stress off your shoulders with what we’re about to show you. This is all you need:

That’s right, folks, that is a Center for Limnology pint glass complete with a Secchi disk bottom and a centimeter ruler printed on the side. We don’t want to overstate this, but it’s basically the adult equivalent of “a Red Ryder BB gun with a compass in the stock and this thing that tells time,” except you can’t shoot your eye out with it.
It can also answer the age-old question, “This is a tasty beverage, but what is its clarity?”

To get the most accurate measurements, place the glass on a light surface (to provide contrast to the darker blue wedges) and then begin pouring until the Secchi disk at the bottom disappears from view. Take note of that measurement. Then enjoy your beverage but keep an eye out for the Secchi’s reappearance and note that, too. Voila, you’ve got your beverage clarity measurement.
So, prost, salud, slainte, cheers and whatever else it is you say when you raise a pint and take citizen science to a whole new level.
We hope you and yours have safe travels, great company and good eats in the weeks to come. Happy Holidays from all of us at the CFL!
